Abstract

The invention discloses a method of anti-interference optimization based on a symmetric de-correlation algorithm, which comprises the following steps: (A) acquiring N input channels and a main input channel, wherein each of the N input channels can be used as a blanking input channel, the remaining N-1 input channels are used as auxiliary channels, and N is an integer greater than 2; (B) acquiringN layers of de-correlation cells and making the adjacent layers of de-correlation cells staggered in turn; (C) correspondingly connecting the N input channels, the main input channel and the N layersof de-correlation cells to form an optimized parallel output processing architecture; and (D) and after anti-interference optimization signal processing of side-lobe cancellation and side-lobe blanking, outputting a main channel signal from a left output end of each de-correlation cell building block in an Nth layer, and outputting a blanking signal from a right output end. The method of the invention can improve the operation efficiency and the regularity of the whole processing architecture, has higher exchange efficiency and flexibility, and can improve the anti-jamming effect of radar.

Description

technical field [0001] The invention relates to the field of radar anti-interference, in particular to an anti-interference optimization method based on a symmetrical decorrelation algorithm. Background technique [0002] Since World War II, radar-related technologies and their widespread use have dramatically changed the world. Most of the mathematical foundations and various computational theories related to the ongoing Artificial Intelligence (AI) revolution actually stem from adaptive radar signal processing (including electronic counter-counter- Measures, referred to as ECCM). [0003] In the professional field of electronic anti-jamming, the two main popular methods are "Sidelobe Cancellation (SLC)" and "Sidelobe Blanking (SLB)". The definition of sidelobe cancellation is to adjust the sidelobe of the main antenna array to make it zero in the direction of the noise interference source. Sidelobe blanking is a mature technique used to deny false target jammers from en...
