介绍了单脉冲测角体制的工作原理，以修正双镜反射面天线为模型，数学推导和图形化显示和差方向图。为实现雷达在副瓣处的角度跟踪，使用基本的数学原理，探讨了雷达副瓣跟踪的机理。

This paper introduces the theory of the mono-pulse angle measurement, specified radars signals on the base of ideal model. In order to realize radar angle tracking at the radar secondary lobe, it draws their graphs and explains the tracking mechanism on radars secondary lobe.
