摘　　要：针对交叉极化角度欺骗干扰的对抗问题,提出了一种利用极化信息进行识别并抑制干扰的措施和方法。首先分析了单脉冲雷达测角和交叉极化角度欺骗干扰的基本原理,然后给出了单脉冲极化雷达的角度测量算法;在此基础上,利用交叉极化干扰在雷达测角系统中不同极化通道响应函数的差异,提出了具有自动识别与抑制交叉极化干扰的实用角度测量算法,给出了应用该算法的具体步骤,理论分析和计算机仿真均证实了此算法的正确性和有效性。A novel method by using polarization information is presented to identify and cancel the cross-polarization angle deception（CPAD）. Firstly, the basic principles of angle measurement by mono-pulse radar and CPAD are analyzed. Secondly, the angle measurement algorithm using mono-pulse polarmetric radar is presented. Then, a novel algorithm of angle measurement, which can auto-identify and suppress CPAD, is presented by using response differences of CPAD in different polarization channels. The validity of this algorithm is verified by theoretical analysis and computer simulations.
