存在质心干扰情况下，普通单脉冲雷达将跟踪干扰与目标的能量重心。在分析目标回波与干扰电磁波相干叠加特性的基础上，提出了一种使用简单极化单脉冲雷达提取目标方位角的方法。该方法简单、实用，但需要获得信号的复数形式以及干扰极化特性的先验知识。仿真结果验证了该方法的有效性。

The conventional monopulse radar will track a power weighted centroid of target and be interfered when centroid-interference is present.This paper proposes a new approach to extract direction-of-arrival(DOA) of the target.This method is simple and effective,though it requires measurements of complex signal and a priori knowledge of the polarization characteristics of interference.The performance of DOA estimator is studied via Monte Carlo simulations.
