摘　　要：在雷达抗干扰设计中,采用空极联合抗干扰方法可以同时对主副瓣干扰进行较好的抑制,但该方法会导致和差方向图畸变,影响目标测角精度。针对该问题,提出一种基于空极联合估计的新方法,该方法在获得干扰信号空极二维信息的基础上设计相应的陷波器,分别在极化域和空域对主瓣和副瓣干扰进行抑制。该方法不会影响和差方向图,保证了目标测角精度。In radar anti-jamming design,the main-lobe and side-lobe interference could be suppressed with the space-polar joint anti-jamming algorithm at the same time,but the distortion of sum-difference patterns could be leaded to and the angle measurement precision of the target is worse.Aiming at this problem,a new method based on space-polar joint estimation is proposed,the corresponding filter on the basis of obtaining the interference's space-polar information could be designed,then the main-lobe and side-lobe interference in polarization and space domain are suppressed respectively.The sum-difference patterns and the angle measurement precision of the target could be achieved better with this method.
