Radar radiation source signal identification method based on multiple sensors

Abstract

The invention provides a radar radiation source signal identification method based on multiple sensors. The method comprises the steps that S01, at least two single-sensor identification systems receive radar radiation source signals in a multi radiation source signal environment to preliminarily sort and identify the radar radiation source signals; S02, a fusion identification system determines whether a single sensor identification result is from the same radar radiation source signal, and if so, follow-up multi-sensor fusion is carried out; S03, a multi-sensor fusion system fuses a lot of single sensor data from the same radiation source to acquire a final multi-sensor identification conclusion; and S04, after the multi-sensor identification conclusion is acquired, a fusion result is evaluated by a fusion evaluation system. According to the invention, the method has the advantages of high identification accuracy and great anti-signal-to-noise ratio characteristic, is suitable for radar radiation source signal identification under low signal-to-noise ratio, and has certain universality for communication signals and sonar signals.

Description

technical field [0001] The invention relates to a radar radiation source signal recognition method in a complex electromagnetic environment, in particular to a multi-sensor-based radar radiation source signal recognition method. Background technique [0002] There are three key technologies in radar emitter signal identification, which are: Electronic Intelligence Reconnaissance (ELINT), Electronic Support Reconnaissance (ESM) and Radar Threat Warning (RWR). To effectively implement electronic jamming, these three technologies are necessary prerequisites and foundations, and their development level has also become an important symbol for judging the advanced nature of radar countermeasure technology. [0003] At present, the research on radar emitter signal recognition is mainly in the stage of recognition based on single sensor. With the development of radar technology, complex system radars are more and more widely used. Using single sensor to identify can no longer accur...

AI Technical Summary

Problems solved by technology

With the development of radar technology, radars with complex systems are more and more widely used. Using a single sensor for identification can no longer accurately and effectively identify complex system radar emitter signals, and the single-sensor identification information is one-sided and uncertain, and the accuracy rate is low.
