Description
Technical Field
The utility model relates to the technical field of radio monitoring, in particular to a radio monitoring direction-finding system.
Background
The types of radio monitoring direction-finding equipment available in the market at present include fixed type, vehicle-mounted type, portable type, handheld type and the like, but are limited by factors such as positions, quantity, frame height, surrounding environment influence and the like, so that the radio monitoring direction-finding equipment has great limitations on the discovery, accurate direction finding and positioning of a radiation source, and the following specific factors are provided.
Difficulty in detecting coverage: both portable and vehicle-mounted detection equipment are detection facilities deployed on the ground, and a detection antenna is generally elevated by about 2-6 meters, so that the detection coverage range is very small. From the detection practice, the detection of a radio radiation source with a transmitting power of tens of watts finds a distance generally in the range of ten kilometers. If the terrain is complex and there are many obstructions, the detection range is smaller, even several kilometers. For a battle area with a depth of tens of kilometers, the detection coverage capability of several kilometers will cause many detection blind areas if a large number of detection devices are not deployed. If a large amount of monitoring equipment needs to be deployed, the required guarantees of the number of equipment personnel, data transmission, damage resistance and the like are difficult to meet.
The accurate positioning of the radiation source is difficult: the direction-finding accuracy of the radio direction-finding equipment deployed on the ground is greatly influenced by the occlusion and reflection of terrain and ground objects, so that a large error is generated in the positioning of a radiation source, and the error often exceeds the bottom line of the position of the radiation source judged by the system, so that the positioning data of the radiation source cannot be informed by a target situation system.
The detection efficiency is low: most of the active monitoring and direction-finding equipment is basically the technology of the nineties of the last century, and does not adopt the advanced detection and integration technology. The signal detection discovery and the signal direction finding are two separated functions, and the broadband parallel processing capability is weak, so that the scanning direction finding efficiency is low. In the case of a complex electromagnetic environment, if the detection device does not have a high-speed scanning direction-finding capability, the detection device cannot dynamically grasp the information of the positions, the emission activity conditions and the like of all radiation sources in real time, and cannot detect low-interception probability signals (frequency hopping signals, radar signals, data link signals and the like).
In a word, the radio monitoring direction-finding system applied in a large number at present is limited by the ground deployment mode, and the capability of accurately and quickly acquiring the position of a radiation source is weak. In order to get rid of the ground limitation, the monitoring and direction-finding equipment is lifted to the air for detection, which is the only way to solve the problem.
The lift-off platform is a difficult problem troubling lift-off detection, and platforms such as captive balloons and unmanned aerial vehicles have been considered in the industry, but the platforms are not adopted due to short dead time, poor tactical performance, inconvenience in control, weak survivability and the like.
The patent application with the application number of CN201510692587.1 provides a monitoring direction-finding system based on an aircraft-borne lift-off interferometer, which comprises a rotor craft, a flight remote controller, monitoring direction-finding equipment and a monitoring direction-finding terminal; the monitoring direction-finding equipment is carried on the rotor craft; the monitoring direction-finding equipment is connected with the monitoring direction-finding terminal through wireless WIFI; the monitoring direction-finding equipment comprises an electronic compass, a GPS antenna, a GPS module, a direction-finding antenna, a receiver, an X86 processing board, a WIFI module and a WIFI omnidirectional antenna; the output end of the GPS antenna is connected with the GPS module, the output end of the GPS module and the output end of the electronic compass are respectively connected with the X86 processing board, the output end of the direction-finding antenna is connected with the receiver, the receiver is connected with the X86 processing board, the X86 processing board is connected with the WIFI module, and the WIFI module carries out wireless communication with the monitoring direction-finding terminal through the WIFI omnidirectional antenna. Although the system can effectively improve the accuracy of monitoring and direction finding, the system only performs functions through the power supply of the aircraft, so that the dead time is short, long-time detection cannot be performed, and the system is easy to detect and find due to the adoption of wireless communication, and the actual application effect is poor.
