摘　　要：从测控雷达主天线、引导天线方向图上的差异进行分析 ,利用主天线增益高、波束窄和自引导天线增益低、波束宽的特点 ,进行了接收信号比较 ,通过合理选用门限 ,在工程应用中利用软件方法实现主、副瓣跟踪识别 。This paper makes an analysis of the difference between the main antenna pattern and the guiding antenna pattern of a TT & C radar first. Then taking advantage of the fact that the antenna gain is high and the beamwidth is narrow for the main antenna and the antenna gain is low, the beamwidth is wide for the self-guiding antenna, the received signals are compared. Through a proper selection of threshold, a software method is proposed for engineering application to realize identification of main-lobe tracking and sidelobe tracking; a function of automatic transfer from sidelobe tracking to mainlobe tracking is also implemented by software method.
