主瓣掩护式干扰下单脉冲雷达目标检测方法
A Target Detection Method for Monopulse Radar under Condition of Main Lobe Cover Interference
摘要
Abstract
Aimed at the problems that as the angle between the target and the jamming line of sight decrea-ses,the anti-jamming performance of monopulse radar decreases noticeably,this paper proposes an im-proved anti-jamming method of monopulse radar based on distributed auxiliary antenna.Distributed auxil-iary antennas are added in the radar system,the maximization of anti-interference improvement factors must be taken as a guideline,and integrated single-pulse radar beams and distributed auxiliary antenna beams are utilized for performing adaptive interference suppression in the beam domain.Finally,CFAR detection is used to verify the anti-interference performance of the proposed algorithm,in comparison with other methods.The numerical simulation results show that the proposed anti-jamming method can effec-tively improve the anti-jamming improvement factor and target detection probability,and has a good anti-jamming performance while the target and interference line of sight are at a small angle.关键词
