摘要
Abstract
The common threshold setting of sidelobe blanking in pulse-compression radar is very simple and has poor anti-jamming performance.Based on the general form of the sidelobe blanking in pulse compres-sion radar,the comprison expression between threshold and radar detection is derived to optimize the selec-tion of blanking threshold and detection threshold.In order to solve the problem when concentrated false tar-gets jamming covers target signal and leads to wrong blanking,put forward a method of “second judgement”which checks the jamming distance cell to estimate whether it’s mixed with target signal.The analysis results show that the optimized threshold performs better than regular one and “second judgement”can solve the wrong blanking resulted from the concentrated false target jamming.关键词
