为了抑制天线副瓣对单通道目标检测的影响,文中通过比较实测天线方向图和回波方向图的特点,提出了利用搜索目标幅度最大值和方位向滑帧统计波束宽度的方法来抑制副瓣干扰,并通过仿真分析验证了算法的有效性。

In order to suppress the effects of antenna sidelobe to single channel target detection, the characteristics of the real antenna pattern and echo pattern is compared in this paper. And then, a method is given which using searching the maximum of the target amplitude and counting the azimuth beam width by frame to frame to suppress the sidelobe jamming. Feasibility of the algorithm is proved by simulation.
