Description

The invention relates to the field of radio engineering and can be used to create deliberate high-power radio interference placed on high-speed and highly maneuverable mobile devices receiving devices of consumer navigation equipment (NAP), operating on the signals of global navigation satellite systems (GNSS), by using a set of radio interference transmitters spaced in space low power with a concentration of the total energy of the radio noise in a given region of space at a given in ervale time.

Hereinafter, we will call both the NAP receiving devices and the mobile means - carriers of this NAP the objects of radio suppression, not excluding the use of the true proper names of these devices, equipment, and means to ensure their unambiguous representation in describing the structure and functioning of the spatially distributed set of means for creating radio interference .

A known electronic warfare system [1], including a central control center for controlling a distributed electronic warfare system and for obtaining target data from a system having a plurality of electronic containers attached to a plurality of aircraft, is capable of listening to targets and interfering with them under the control of a central control center.

Known network-centric spatially distributed system based on small-sized intelligence and interference modules [2], consisting of a control center and data processing of a spatially distributed intelligence and interference system, small-sized intelligence and interference modules located in close proximity to electronic equipment.

These electronic warfare systems and a network-centric spatially distributed system based on small-sized reconnaissance and interference modules provide radio suppression of radio communications (direct, trunking, cellular, radio-relay, tropospheric, satellite) and active ground-based radar, characterized by a priori certainty and relative constancy of location , as well as the presence in their composition of functionally significant devices for the formation, amplification and radiation of a radio signal ov.

A common disadvantage of these systems is that they determine the object of suppression by radio emission of the suppression objects themselves and do not suppress NAPs operating on GNSS signals located on high-speed and highly maneuverable mobile devices.

Spatially distributed complexes of radio interference generating means for suppressing NAPs based on GNSS signals located on high-speed and highly maneuverable mobile devices were not found in an open publication from all available information sources.

The technical solution for the creation of radio interference for NAPs operating on GNSS signals placed on high-speed and highly maneuverable mobile devices is performed when creating a spatially distributed complex of radio interference generating means, consisting of a control point having coordinate-time and navigation support equipment, power supply unit, remote control control unit, display unit, transmitting antenna, receiving antenna, radio station control channel, special computer that performs the functions defined a region of the location of the radio suppression and control object that is predicted for a given time interval, spaced apart in the space of reconnaissance stations having a transmitting antenna, a receiving antenna, a control channel radio station, power supply unit, time-coordinate and navigation support equipment, equipment for detecting and determining the location of a radio suppression object with an antenna, a special calculator that generates and transmits operation initialization codes the equipment for detecting and determining the location of the radio jamming object, and the radio interference stations collectively spaced in space, having a transmitting antenna, a receiving antenna, radio stations of a control channel, power supply unit, time-coordinate and navigation support equipment, a radio noise transmitter control unit, a radio noise transmitter with a radio noise antenna , device for angular orientation of the radio interference emission antenna, control unit for the angular position of the radio interference emission antenna, special calculation an object providing the angular orientation of the main lobes of the radiation patterns of antennas emitting radio noise, creating in the given region of the location space of the radio jamming device for the navigation equipment of consumers operating on the signals of global navigation satellite systems, the required level of total radio interference power, taking into account the optimization of the applied order of radio interference stations placed in space according to their location and quantity, as well as the time schedules of the work of stations p radiation interference.

The invention is illustrated by drawings.

, where k is the serial number, and K is the number of reconnaissance stations in COMPLEX).

The control center 5 consists of time-coordinate and navigation support equipment (CVC) 6, a power supply unit 7, a control panel 8, a display unit 9, a transmitting antenna 10, a receiving antenna 11, a radio station of the control channel 12, a calculator 13.

The radio interference station 3 consists of a transmitting antenna 14, a receiving antenna 15, a radio channel for the control channel 16, an electrical power supply unit 17, time-coordinate and navigation support equipment 18, a radio interference transmitter control unit 19, a radio interference transmitter 20 with a radio interference antenna 21, and an antenna angular orientation device radiation interference 22, the control unit of the angular position of the antenna radiation interference 23, special computer 24.

Reconnaissance station 4 consists of a transmitting antenna 25, a receiving antenna 26, a radio station for the control channel 27, an electric power supply unit 28, time-coordinate and navigation support equipment 29, radar equipment for detecting and locating radio suppression objects 30 with antenna 31, and a special computer 32.

The power supply units 7, 17, 28 provide power to the components of the control point 5, radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N , reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K, respectively, by converting the power supplied to them ( industrial power supply network, diesel-electric generators, storage batteries, not shown in the drawings) primary current flow to the ensemble of stabilized secondary power supply voltages of the required quality (provided load currents, levels and time parameters are rejected minutes from the mean value, the amplitude-frequency characteristics of interfering components, and the like) under the action of external disturbing mechanical and environmental factors. As the considered power supply units, as an example of their technical feasibility, it is possible to use commercially available products BP-U1 PRTK.435118.001, OKP code 65 5429 2105, in which technical and structural-artistic solutions are applied [3, 4].

The equipment of coordinate-time and navigation support (KVNO) 6, 18, 29 is intended for:

determination of the ensemble of coordinates of a mobile vehicle (MS) - carrier of the COMPLEX component (sets V _PU - for control point 5, sets V _{SP n} - for radio interference station 4 _n , sets V _{SR k} - for reconnaissance station 4 _k ), including: latitude, longitude, height (relative to the reference level in the applied coordinate system) of the positioning point of the MS, the azimuth of the longitudinal axis, the angles of the longitudinal and transverse slopes of the MS;

issuing highly stable sequences of pulses with reference to the single time scale for synchronizing the functioning of COMPLEX components.

As the KVNO equipment under consideration, as an example of its technical feasibility, it is possible to use the mass-produced product "Navigation complex" Landmark "PRTK.462414.007, OKP code 65 4326 3000, providing:

determination of the MS coordinate ensemble by real-time continuous determination by non-autonomous (receivers based on the signals of global navigation satellite systems (GNSS) GLONASS and GPS and the long-wavelength pulse-phase radio navigation systems Chaika and Loran-C) and autonomous (gyrohorizon compass, geomagnet digital compass, odometer) with navigation sensors with automatic integration of measurement results (numbering) of coordinates and mutual correction of the functioning of navigation dates chikov;

the formation and generation of sequences of clock pulses using GNSS signals and built-in highly stable reference generator.

The product “Navigation complex“ Landmark ”implements technical solutions [5-17] and programs [18-24].

The radio stations of the control channel 12 (together with the transmitting antenna 10 and the receiving antenna 11), 16 (together with the transmitting antenna 14 and the receiving antenna 15), 27 (together with the transmitting antenna 25 and the receiving antenna 26) are means of ensuring intercomponent information exchange (codograms - commands and codograms-reports) between control point 5, radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N , reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K.

The main requirements for these radio stations are: the ability to work in a data exchange mode (transmitting and receiving information in digital form) according to an agreed protocol; the ability to provide stable (in the conditions of an evolving electromagnetic environment, including radio emissions from radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N ) radio communications at distances determined by the positions of COMPLEX components, using the required number of relayings in the direct communication directions or via reference communication nodes ( base stations, satellite repeaters) of general or special purpose network communication systems; correspondence of the throughput to the traffic of data exchange in the directions between the components of the COMPLEX.

As the considered radio stations, depending on the size of the COMPLEX position area, modern means of direct short- and ultra-short-wave mobile radio communication [25], radio relay communication [26], mobile satellite subscriber terminals [27] and cellular communication [28] are possible.

In view of the foregoing, the use of the terms “transmitting antenna”, “receiving antenna” in the case of the use of radio means in which the transmission and reception of radio signals through one antenna-feeder device is used in the further description of the operation of the COMPLEX is caused only by the desire to unambiguously interpret the direction of the information flow between the components COMPLEX.

In addition, we note that in the segment of intra-complex information exchange, the channels of which are deployed using radio stations 12, 16, 27, a synchronous address communication method is implemented. Moreover, the synchronization of communications is used not only to regulate the exchange of data between the components of the COMPLEX, fending off conflict situations characteristic of the asynchronous method of communication, but also to provide autonomous intra-complex synchronization, which reserves the possible loss of synchronization of the functioning of the components of the COMPLEX when the KVNO equipment fails due to its non-absolute technical reliability or disruption in receiving GNSS signals.

In terms of the technical feasibility of special computers 13, 24, 32, it is worth highlighting the feasibility of the hardware component - a means of electronic computing and mathematical software (MPO).

As a hardware component of special computers 13, 24, 32, it is quite appropriate to use a commercially available product BSV-3 PRTK.466535.004, OKP code 66 2451 4000.

The closest analogue of MPO of special calculator 13 is MPO of a commercially available product R-330KMA PRTK.468329.001, OKP code 65 5462 4000 - control point of the automated interference complex R-330M1P PRTK.462719.001, OKP code 65 5419 9000.

The closest analogue to MPO of special computers 24, 32 is MPO of a commercially available product R-330ZH PRTK.460010.003, code OKP 65 5424 9000 - an automated jamming station for subscribers of the INMARSAT satellite communication system and the NAVSTAR satellite radio navigation system.

The control unit of the interference transmitter 19 provides information and technical pairing of the special computer 24 with the radio interference transmitter 20.

The control unit 19 receives the codograms of the radio interference transmitter control commands 20 transmitted by the special computer 24 in the standard serial interface format, and in accordance with the built-in program, implements the operation mode of the radio interference transmitter 20 specified by the command by transmitting to its components codograms and signals in the formats of the corresponding specialized interfaces.

In addition, the control unit 19 collects, processes, stores and issues data to the special computer 24 about the technical condition of the components of the radio interference transmitter 20.

The control unit for the angular position of the radio interference emission antenna 23 performs the functions similar to the control unit of the radio interference transmitter 19 for controlling and collecting data on the technical condition of the angular orientation device of the radio interference radiation antenna 22.

The technical implementation of the control unit of the radio interference transmitter 19 and the control unit of the angular position of the radio interference radiation antenna 23 can be carried out on the basis of the commercially available KOKS product (command and signal processing controller) PRTK.466535.006 with software of the type [29, 30].

The radio interference transmitter 20 with the radiation antenna of the radio noise 21 provides the formation of interfering signals with parameters F _{SP n} , their amplification to the level P _{SP n} and radiation into the space region characterized by the antenna radiation pattern parameters G _{SP n} .

.The studies [31, 32] show the feasibility of the design and technical implementation of interference transmitters 20 with radio interference radiation antennas 21 in the form of active transmitting phased array antennas (APFAR) and ensuring the required efficiency in the area of responsibility of a 3 _n radio interference station by using several APFARs that are operatively oriented in azimuthal and elevation planes according to

.

Moreover, descriptions of technical solutions implemented in APFAR and their structural and technical performance are given in [33-43], and objective evidence of development in production are serial samples of APFAR-S1 PRTK.464657.002 products, OKP code 65 5429 0837, APFAR-S2 PRTK.464657.002-01, OKP code 65 5429 0838, MPP PRTK.464657.004, OKP code 65 5428 1281.

.The device of the angular orientation of the radiation antenna interference 22 provides the implementation of the angular position of the radiation antenna interference (taking into account the above - APFAR) in the azimuth and elevation planes according to

.

The structural and technical implementation of the device 22 can be carried out on the basis of electromechanical drives, one of the many variants of which are described in [44].

Radar equipment for detecting and determining the location of radio jamming objects 30 with an antenna 31 provides data on spatial coordinates and motion path parameters (C _{OD k} ) of a radio jamming object 2 _m .

The platform for the technical implementation of radar equipment for detecting and determining the location of radio jamming objects 30 with antenna 31 is active radar equipment, in particular a three-coordinate radar station with trace processing of information of the decimeter wave range 59N6-1 [45].

COMPLEX operates in a regular single-cycle operation as follows.

COMPLEX components: control center 5, radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N , reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K , after making a march from the area of concentration or performing a maneuver to relocate, are in the set position areas in readiness for function as intended. Power supply from blocks 7, 17, 28 is supplied to all elements of the workable components of the COMPLEX.

The operator of the control center 5 from the control panel 7 enters into the special computer 13 a command to initialize the procedure for collecting data on the location and operability of the COMPLEX components (hereinafter in brief - the SDPR command).

The special computer 13, having received the SDPR command, generates and transmits, via intra-site communication lines, the codograms of the operability request of the KVNO 6 equipment and the radio station of the control channel 12 with the transmitting antenna 10 and the receiving antenna 11 connected to it. In response to receiving the codogram, the KVNO 6 equipment and the radio station 12 form and transmit through the lines of intra-object communication to the address of the special computer 13 data autonomous technical diagnosis. The special computer 13, having accepted this data, evaluates the health status of the control room 5 according to a specified criterion and gives them to the display unit 9 to inform the operator about the continued execution of the SDPR command (in the case of the health of the control center 5) or the need to restore the health of the detected faulty elements of the control center 5.

A further description of the COMPLEX operation is given with the assumption that the control center 5 is unconditionally operational without focusing on the implementation of measures to maintain the centralized COMPLEX control by quickly restoring the control center 5, using the backup control station, transferring the COMPLEX control functions to one of the radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N or intelligence stations 4 ₁ , 4 ₂ , ..., 4 _K.

Along with the data autonomous technical diagnosis equipment KVNO 6 outputs a data spetcvychislitelej 13 ensemble MS coordinate control point 5 (B _PU) and a sequence of clock pulses for the operation in the normal mode as a control item elements 5 and the system as a whole.

The next step in the implementation of the SDPR command is the generation by a special calculator of 13 codograms of a request for data on the location and operability of radio interference stations 3 ₁ , 3 ₂ , ..., 3 _N and reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K (ZDPR codograms), which are a special calculator 13 in In accordance with the protocol of the intra-complex information exchange, it transmits via the radio station the control channel 12 and the transmitting antenna 10 to the address of all the above-mentioned components of the COMPLEX.

Radio signals containing the ZDPR codogram, through the receiving antenna 15 and the radio station of the control channel 16, enter the special computer 24 of each functional part of the named telecommunication-control segment of the radio interference station 3 ₁ , 3 ₂ , ..., 3 _N , and through the receiving antenna 26 and the radio station control channel 27 - to the special calculator 32 of each operational part of the named telecommunication-control segment of the intelligence station 4 ₁ , 4 ₂ , ..., 4 _K.

Having adopted the ZDPR codogram, the special computer 24 from the radio interference station 3 _n generates and transmits via the intra-object communication lines the codograms of the operability request of the KVNO 18 (KZR-18) equipment, the radio interference transmitter control unit 19 (KZR-19), and the radio noise interference antenna angular position control unit 23 (KZR-23).

In response to the received KZR-18 codogram, the KVNO 18 equipment generates and transmits to the address of the special computer 24 a report codogram containing autonomous technical diagnostics data, as well as (if operational) data on the coordinate ensemble of the radio interference station carrier object 3 _n (V _{SP n} ) . In addition, the KVNO 18 equipment issues 24 sequences of clock pulses to the special computer 24 to ensure the normal operation mode of the radio interference station 3 _n .

Having accepted the KZR-19 codogram, the radio interference transmitter control unit 19 generates and transmits to the radio interference transmitter 20 the codogram of a request for data on the technical condition of its components (KZR-20).

Based on the received data on the technical condition of the components of the radio interference transmitter 20, the radio interference transmitter control unit 19 generates and transmits to the address of the special computer 24 a report codogram on the operability or inoperability of the radio interference transmitter 20.

Having adopted the codogram KZR-23, the control unit for the angular position of the radio interference radiation antenna 23 performs the procedure of diagnosing the technical condition of the angular orientation device of the radio interference radiation 22 and generates and transmits to the address of special computer 24 a report codogram on the operability or inoperability of the radiation antenna angular orientation device radio interference 22.

If you don’t receive within a given time interval codograms of reports from the KVNO 18 equipment, from the radio interference control unit 19 or from the radio interference 23 control unit for the angular position of the radiation antenna, the special computer 24 decides on the inoperability of the corresponding chain of elements.

On the basis of the received data in the _{SP n} and the diagnostics data on the technical state of the elements 19, 20, 22, 23, the special computer 24 generates a codogram of the report on the location (In the _{SP n} ) and the operability (W _{SP n} ) of the radio interference station 3 _n (the DPR-3 _n codogram) , which transmits through the radio channel control channel 16 and the transmitting antenna 14 to the address of the control point 5.

Having adopted the ZDPR codogram, the special computer 32 from the 4 _k reconnaissance station generates and transmits, via the intra-object communication lines, the codograms of the operability request of the KVNO 29 (KZR-29) equipment and the equipment for detecting and determining the location of the radio suppression object 30 (KZR-30).

In response to the received KZR-29 codogram, the KVNO 29 equipment generates and transmits to the address of the special computer 32 a report codogram containing autonomous technical diagnostics data, as well as (in case of operability) data on the coordinate system of the reconnaissance station MS 4 _k (V _{SR k} ). In addition, the KVNO 29 equipment issues a sequence of clock pulses to the special computer 32 to ensure the normal operation mode of the 4 _k reconnaissance station.

Having adopted the KZR-30 codogram, the radar equipment for detecting and determining the location of the radio jamming objects 30 performs an autonomous diagnosis of the technical condition and, based on its results, generates and transmits to the address of the special computer 32 a codogram of the report on operability or inoperability.

If the codograms of reports from the KVNO 29 equipment or from the radar equipment for detecting and determining the location of radio suppression objects 30 are not received within a specified time interval, the special computer 32 decides on the inoperability of the corresponding element of the 4 _k reconnaissance station.

Based on the data obtained in _{CP k} and diagnostic data on the technical condition of the radar detection and location of radio jamming objects 30, special computer 32 generates a codogram of the report on the location (In _{CP k} ) and operability (W _{CP k} ) of the 4 _k reconnaissance station (DPR-4 _c code ), which transmits through the radio channel control channel 27 and the transmitting antenna 25 to the address of the control point 5.

Radio signals containing the DPR-3 _n (DPR-4 _k ) codograms, through the receiving antenna 11 and the radio station of the control channel 12, are fed to a special computer 13, which generates data arrays about the spatial coordinates and technical condition of the radio interference stations (V _SP , W _SP ) and stations intelligence (In _SR , W _SR ). In this case, the failure to receive the DPR-3 _n (DPR-4 _k ) codogram for a given time interval is interpreted by special computer 13 as a fact of a technical malfunction (inoperability) of the 3 _n radio interference station (4 _k reconnaissance station). Arrays of data In _SP , W _SP , In _SR , W _SR special calculator 13 gives the display unit 9 for visualization in graphical and text formats.

The operator of control center 5, taking into account the received data of V _SP , W _SP , V _SR , W _SR, according to the requirements of the COMPLEX application plan or an extraordinary instruction from a higher governing body, enters from the control panel 7 into special computer 13 a command to initialize the procedure for collecting data on spatial coordinates and motion path parameters (With _OP ) of the radio suppression object 2 _m (hereinafter briefly - the SDOP command).

Special agent 13, having adopted the SDOP command, generates codograms for requesting data on spatial coordinates and motion path parameters of the radio suppression object 2 _m (CROP code), which, in accordance with the protocol of the intra-complex information exchange, transmits via the radio channel of the control channel 12 and transmitting antenna 10 to the address of efficient reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K.

Radio signals containing the SRTP codegram, through the receive antenna 26 and the radio station of the control channel 27, are sent to the special computer 32 of each operational intelligence station 4 ₁ , 4 ₂ , ..., 4 _K.

Having adopted the SROP codogram, the special computer 32 from the 4 _k reconnaissance station generates and transmits, via the intra-object communication lines, the codograms for initializing the operation of the radar equipment for detecting and locating radio suppression objects 30 (KOP-30).

according to purpose on a time interval (t _Hi , t _Ki ) with parameters of emitted radio interference

and the parameters of the angular orientation of the antenna of the radio interference radiation 21, set

; кодограмму задания блоку управления передатчиком помех 19 (КУП-19), содержащую определенные предписанием параметры радиопомех

, которые должны быть сформированы и усилены передатчиком радиопомех 20.Having received and processed the SPOP command, the special computer 24 generates and transmits via intra-object communication lines: the codogram of the task to the control unit for the angular position of the radio interference radiation antenna 23 (KUA-23) containing the angular orientation parameters of the radio interference radiation antenna defined by the prescription 21

; the codogram of the task to the control unit of the interference transmitter 19 (KUP-19), containing radio interference parameters determined by the regulation

to be formed and amplified by the radio interference transmitter 20.

codograms and signals in the formats of specialized control interfaces for the functional modules of this device, in particular [44]: electromechanical drives, control sensors, stabilization devices, etc.

The radio noise generated and amplified by the transmitter 20 is emitted by the antenna 21 in the direction of the region of space 1.

, обеспечивается уровень суммарной мощности некогерентных радиопомех не ниже требуемого для гарантированного радиоподавления НАП.Thus, in the space region of 1 _{m, the} set of radio interference stations included in the outfit

, the level of the total power of incoherent radio interference is ensured not lower than that required for guaranteed radio suppression of NAP.

The COMPLEX's work in creating radio noise in single regions of space 1 _m for non-intersecting time intervals (t _Ki ≤t _{Hi + 1} , i = 1, 2, 3, ...) seems to be a sequence of implementations of the above-mentioned regular single-cycle operation.

и приоритета (важности) объектов радиоподавления 2_m.If it is necessary to create radio interference simultaneously in several areas of 1 _m space, the COMPLEX operation is represented as a superposition of parallel (quasi-parallel) implementation of several regular single cycles of operation. In this case, the task of reconnaissance stations 4 ₁ , 4 ₂ , ..., 4 _K is to collect data on the spatial coordinates and parameters of the trajectory of movement of all radio suppression objects located in the COMPLEX's area of responsibility 2 _m . The task of control point 5 is the dynamic optimization of the formed orders of radio interference stations

taking into account their current location and technical capabilities to create radio interference, as well as the consistent reduction in the resource (primarily the number) of radio interference stations for inclusion in the next outfit

and priority (importance) of radio suppression objects 2 _m .

In the extreme case, if it is impossible to rank radio suppression objects 2 _m by priority, if it is impossible or inexpedient to localize areas of the radio jamming space 1 _m due to the significant number of spatially distributed radio suppression objects 2 _m , the COMPLEX will consist in forming the widest (approaching a circular) region of space in the azimuthal plane creating radio interference.
