摘　　要：旁瓣相消的目的是减弱雷达旁瓣接收到的干扰信号，它通过配置辅助天线改变雷达天线的接收方向图来实现。本文用最小二乘算法计算出了一种带有两个辅助天线的旁瓣相消系统的自适应权值，并利用Matlab对该系统的空域和频域响应进行了仿真和分析，结果发现干扰的方位和带宽都会影响相消系统的响应特性。The objective of the side-lobe-canceling （SLC） is to weaken the jammers received through the side lobes of the radar. It is accomplished by equipping the radar with auxiliary antennas to modify the receiving pattern of the radar antenna. The adaptive weight of a SLC system with two antennas is calculated by using the least square method in this paper, and the space and frequency domain response of the system is simulated and analyzed with Matlab. The result shows that azimuth and bandwidth of jammers affect system response.
