以机械转动改变天线指向从而实现方位跟踪的ECM接收系统，在大信号条件下容易出现旁瓣跟踪问题，本文提出几种可能的解决方法。这些方法利用跟踪灵敏度的调整、主辨识别措施以及综合手段，达到较好的效果。
The ECM receiving system that changes the antenna pointing by mechanical rotation to achieve azimuth tracking is prone to sidelobe tracking problem under large signal conditions. Several possible solutions are proposed in this paper. These methods use the tracking sensitivity adjustment, identification identification measures and comprehensive means to achieve better results.
