Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further details:
With reference to accompanying drawing 1, the utility model proposes a kind of mixed model meteorological detection system based on multifunction array radar, a kind of mixed model meteorological detection system based on multifunction array radar, including several radar nodes, each radar node includes the antenna 11 being sequentially connected with, transmitting-receiving subassembly 12, Up/Down Conversion device 13 and medium-frequency receiving and sending activator 14, it is characterized in that: described medium-frequency receiving and sending activator 14 outfan is sequentially connected with data intake device 15, radar data processor 16 and display module 2, some radar nodes are sequentially connected with, form radar netting 1, described radar netting 1 input is connected with radar control and Operating Interface Module 3 by network.Described transmitting-receiving subassembly 12 includes receiving unit 121, power amplifier 122, digital-to-analog circuit 123, power supply control 124, cooling system 125 and transmitter unit 126.Described Up/Down Conversion device 13 includes upconverter 131 and low-converter 132, described transmitting-receiving subassembly 12 outfan respectively with upconverter 131 and low-converter 132, described upconverter 131 outfan medium-frequency receiving and sending activator 14 connects, and described down coversion 132 device input encourages 14 devices to be connected with medium-frequency receiving and sending.
The outfan of medium-frequency receiving and sending activator 14 can also be connected to data intake device 15, and the outfan of described data intake device 15 is connected with sea-surface target processor, described targets in ocean display module (being suitable for NMEA agreement) in turn；Described radar netting 1 is connected with a sea surveillance system central processing unit, some user terminals successively by the Internet.This utility model is not shown.
The air traffic control radar being arranged on coastline comprises the antenna of a mechanical rotation in certain direction, sweep speed may be up to 5 seconds one turn, this antenna can launch and receive low wave beam and high beam signal: low wave beam is that high wave beam is for the space of High aititude height in covering for covering earth's surface to intermediate altitude height space.For the air traffic control radar on coastline, low wave beam can be concurrently detected ground target and aerial target.Antenna can to the monitoring field emission series of electromagnetic pulse paid close attention to, and electromagnetic pulse can be reflected to antenna by the object in this monitoring region.The radar signal that some object reflects is to need to be paid close attention to, then be referred to as " target ", and the radar signal that other remaining objects reflect is referred to as " clutter ", namely the noise in radar system.Earth's surface target is considered as the noise in existing area control radar system, is therefore removed in its signal processing.Generally, the radar data collected from antenna 11 carries out pretreatment by a band filter Data-Link, removes at the outside irrelevant signal of radar data or noise, then radar data solution is transferred to if radar data, then carries out the analog digital conversion of radar data.Now, radar data is demodulated to base band data (I/Q data), and base band data (I/Q data) is carried out low-pass filtering and sampling.This data can be sent to aerial target processor 15 and be further processed, and are used for detecting and following the tracks of aerial target.
A kind of mixed model meteorological detection system based on multifunction array radar, mainly comprises the steps that
1) identify and list great meteorological activity: the user of radar or operator are by the selected meteorological activity of radar control and Operating Interface Module, and radar control and Operating Interface Module load the characteristic parameter of corresponding meteorological activity and the pre-determined model of its moving situation automatically.In this step, the user of radar or operator important meteorological activity is selected.These important meteorological activities include hurricane, tornado, the bird in groups close to traffic pattern and the smog etc. from forest.For under the weather activity that each is important, system loads the pre-determined model of its feature and its moving situation automatically.
2) the great meteorological activity that radar netting location is selected；According to the feature that selected great weather is movable, each radar netting can carry out all standing scanning and go to determine if exist；Once identified, the orientation of the current location at its place, distance and highly all can be recorded.
3) radar netting prediction steps 2) in selected great meteorological activity shift position in future；Predefined pattern the ambient parameter such as wind speed and direction etc. according to respective settings is used to estimate the following shift position of the important meteorological activity selected.
4) radar netting updates scanning scene；In this link, the position pre-estimated of great meteorological activity can be incorporated the parked position of radar scanning scene or in the time, and on this parked position specified by radar beam-pointing be likely to occur great meteorological condition and region.It is likely to occur the region area of great meteorological condition to be typically larger than from model, estimate the area obtained.Reason adds the variance of estimation when being incorporate.Under this mode, at the whole area of coverage of radar, the finite region that only one of which is little is scanned by radar, and therefore the time of scanning every time can shorten.Therefore radar resource may be used for other application tasks, so just can promote to realize a multi-functional phased array of real work.
5) newly scan scene for next scan period operation, collect Data Concurrent and send in radar data processor；Will through radio frequency receiver from corresponding to echo-signal that the movable parked position of significant weather received by antenna, low-converter and intermediate-frequency receiver/activator (REX) module.The output of REX is referred to as the baseband signal of I/Q data.The data of IQ are sent to weather radar data processor by network interface, just can be used to detection and position important meteorological activity.These data include the corresponding head pulse fileinfo relevant to great meteorological activity, the beam data of pulse recurrence frequency and positive north antenna direction.Before data intake device receives these information, decode it after checking its effectiveness as the readable data form of radar data processor (RDP).The responsibility of data intake device is identification and corrects the shortage of data owing to network service or the other reasons of over loading cause or mistake, and stops these the incorrect data of transmission to RDP.
6) digital radar processor processes data and detection, position great meteorological activity and generate two grades and three grades of Meteorological Products；This data stream then passes through the process of radar data processor (RDP) and generates second and third level Meteorological Products, including reflectance, differential reflectance, correlation coefficient, spectrum width, radial velocity and differential phase shift.Third application Gauss model self-adaptive processing is filtered, and eliminates clutter content in data.By the second level and the 3rd series products, it is possible to be accurately positioned important meteorological activity.Target complex to birds and other biological, RDP is equipped with target tracker and is used for detecting and following the trail of them.
7) display module is used for receiving two grades and three grades of Meteorological Products and by step 4) state that updates and the movable position of important weather, and show on map；Meteorological activity display is for receiving the state of two grades and three products and renewal and the position that significant weather is movable, and shows on map.This display provides the update status of real-time weather harm to operator.
8) step 3 is returned).
It is above the preferably enforcement of utility model has been illustrated, but utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the premise without prejudice to this utility model spirit, and these equivalent modification or replacement are all contained in the application claim limited range.
