Abstract
The present invention for it is a kind of based on multiple-beam radar bigness scale to communication access method, be related to and a kind of be based on multiple-beam radar Fast Coarse direction finding technology.By introducing secondary beam, for quickly adjudicating radiant source target whether in this beam coverage, improve to radiation source direction finding efficiency, while according to this radar beam major-minor ratio characteristic effectively reject wave beam secondary lobe alignment radiation source situation, realize multi-beam bigness scale to method.The method does not need radar complete scan one week, as long as radiant source target is general orientation where can determine that radiation source in this beam coverage, substantially increases multiple-beam radar bigness scale to efficiency.
Description
Technical field
The present invention relates to radar slightly to technology.
Background technology
With the development of ECM, in modern war, the requirement to radar performance becomes more and more higher.Radar
When carrying out passive detection, typically using ring sweep amplitude maximum method to radiation source progress bigness scale to.I.e. after radar scanning one week, choosing
Go out to meet the orientation and amplitude information of each parameter of radiation source (carrier frequency, repetition and pulsewidth etc.), and find out corresponding to Amplitude maxima
Orientation, so as to complete the bigness scale to radiation source to.This method needs one week orientation that just can determine that radiation source of radar scanning, no
Can be lock onto target in this radar beam alignment radiation source for the first time, bigness scale is to less efficient, it is impossible to meets high performance
The requirement of quick direction finding in radar system.
The characteristics of present invention is using the synthesis of phased-array radar multi-beam, introduces two positioned at the auxiliary of beam coverage border
Wave beam is helped, as long as radiation source is located in the range of this beam scanning, you can the amplitude characteristic according to multiple wave beams are received determines spoke
Penetrate source general orientation, can solve ring sweep amplitude maximum method have to scan through could complete after one week bigness scale to the shortcomings that, make thunder
Up to communication access can be rapidly completed.
The content of the invention
It is an object of the invention to provide it is a kind of based on multiple-beam radar bigness scale to communication access method.
The technical solution for realizing the object of the invention is：First, N number of reception wave beam is carried out radiation source parameter by radar
Match somebody with somebody and amplitude calculates, co-continuous covering M degree bearing ranges；Then the range value sampling of N number of wave beam is carried out once every N number of clock
Compared with, when the ratio of the maximum wave beam of range value and the big wave beam of range value time is more than according to thresholding of the radar major-minor than determination,
It is judged as that main lobe is aligned, finally, if wave beam where main lobe is non-critical wave beam, wave beam where main lobe is that radiation source place is big
Orientation is caused, if wave beam where main lobe is the border of critical wave beam, i.e. angle of coverage, then wave beam where main lobe can not be judged to radiating
General orientation where source, should carry out the scanning of next beam coverage.The method does not need complete one week of radar scanning, as long as
General orientation where radiant source target can determine that radiation source in this beam coverage, substantially increases multiple-beam radar
Bigness scale is to efficiency.
Brief description of the drawings
Fig. 1 multi-beams scan schematic diagram.
Fig. 2 is based on the bigness scale of multiple-beam radar to flow chart.
Embodiment
Multi-beam scanning schematic diagram is as shown in Figure 1.In the scanning of beam coverage, N number of reception wave beam is shared, its
In to have two be critical wave beam, the border of angle of coverage.First time scanning beam coverage be figure in 1~N of numbering, its medium wave
Beam numbering is 1, N reception wave beam is critical wave beam, and it is N-2 effectively to cover number of beams, and wave beam numbering is 2~N-1；It is next
Secondary scanning beam coverage is numbering N-1~2N-2 in figure, and wherein wave beam numbering is that N-1,2N-2 reception wave beam are critical
Wave beam, it is N-2 effectively to cover number of beams, and wave beam numbering is N~2N-3.
It is as shown in Figure 2 to flow chart based on the bigness scale of multiple-beam radar.First, radar is radiated N number of reception wave beam
Source parameter matching and amplitude calculate, co-continuous covering M degree bearing ranges.Then the width of N number of wave beam is carried out once every N number of clock
Angle value is sampled compared with, is determined when the ratio of the maximum wave beam of range value and the big wave beam of range value time is more than according to radar major-minor ratio
Thresholding, be judged as main lobe be aligned.Finally, if wave beam where main lobe is non-critical wave beam, wave beam where main lobe is to radiate
General orientation where source, complete radiation source bigness scale to；If wave beam where main lobe is critical wave beam, wave beam where main lobe can not be sentenced
General orientation where being set to radiation source, should carry out the scanning of next beam coverage.
