摘　　要：自适应波束形成技术是相控雷达的关键技术,能够最大化接收信号,并且防止旁瓣干扰。但在干扰由天线方向主瓣进入时,此技术性能会显著降低,对雷达检测性能造成极大影响。对于雷达主瓣干扰抑制问题,文章从当前抗主瓣干扰方式进行分析,主要是主动对抗及被动抑制两方面,重点探究相控阵雷达抗主瓣干扰技术。Adaptive beamforming technology is the key technology of phased radar,which can maximize the received signal and prevent side lobe interference.However,when the interference enters from the main lobe of the antenna,the performance of this technology will be significantly reduced,which will have a great impact on the radar detection performance.For the problem of radar main lobe interference suppression,this article will analyze the current anti-main lobe interference methods,mainly in two aspects:active countermeasures and passive suppression,and focus on the anti-main lobe interference technology of phased array radar.
