摘　　要：反舰导弹末制导雷达在抗干扰能力方面仍存在一些不足,对雷达回波信号进行双极化处理,是末制导雷达提高抗干扰能力的一种有效的技术途径。论文论述了雷达信号极化检测原理,通过舰船目标与典型干扰的极化特征差异对比,结合试验数据仿真结果分析发现,舰船目标的去极化特性较弱,采用双极化处理手段,对末制导雷达跟踪过程中的目标识别与干扰信号剔除具有显著作用。There are still some deficiencies on anti-jamming capability of anti-ship missile terminal guidance radar,dual-polarized radar echo signals is an effective technical approach to improve anti-interference ability of terminal guidance radar.In this paper,the principle of radar signal polarization detection is discussed.By comparing the polarization characteristics of the ship target and the typical interference,the experimental results show that the depolarization characteristics of the ship are weak.The use of dual-polarization processing means has a significant effect on the target recognition and interference signal rejection in the terminal guidance radar tracking.
