Abstract

The invention discloses a radar electronic anti-jamming system integrating side-lobe blanking and side-lobe cancellation. The system comprises an N input-2*N output processing architecture, wherein Nis an integer greater than 2. The N input-2*N output processing architecture comprises N input channels, N-1 layers of de-correlation cells and 2*N blanking output channels. Each of the N input channels can be used as a blanking input channel, and the remaining N-1 input channels are used as auxiliary channels. The adjacent layers of de-correlation cells are staggered in turn. Each layer of de-correlation cells comprises N de-correlation cell building blocks arranged horizontally. Each de-correlation cell building block has a left input end, a right input end, a left output end and a right output end. The N input-2*N output processing architecture is a two-dimensional plane architecture. The system can remove the data broadcasting line, improve the operation efficiency and improve the regularity of the whole processing architecture, and has high exchange efficiency and flexibility.

Description

technical field [0001] The invention relates to the field of radar electronic anti-jamming, in particular to a radar electronic anti-jamming system integrating side lobe blanking and side lobe cancellation. 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 ...
