单脉冲雷达因其测角精度高，抗干扰能力强，使其得到了广泛的应用。而对于接收支路要求不太严格的双平面振幅和差式单脉冲雷达，更是备受青睐。文中从四喇叭天线的位置坐标关系，详细分析了双平面振幅和差式单脉冲雷达信号处理过程以及三通道幅相不一致性的影响，并且进行了相应的仿真，为工程实现带来了很大的便利。另外，该分析方法还具有一般性，即也可应用于单个平面的情况。

Monopulse radar is widely used for its high angle measurement and powerful anti-jamming performance. Sum and difference patterns of amplitude dual - plane monopulse radar is more widely paid attention to using because that it doesnt need to have strict receive channel. In this paper, the signal processing of sum and difference patterns of amplitude dual - plane monopulse radar and the effect of amplitude-plane non-consistency are analyzed from the coordinates relationship of four-horn antenna at length, and its corresponding simulation is verified, which bring convenience to engineering implementation. Moreover, it has generality for this analysis method, this is to say, it is also used for single-plane monopulse radar.
