Method of interference suppression based on polarization digital beam formation for the guidance radar

提出了一种极化相控阵弹载雷达系统,以提高导弹制导雷达的电子战性能。该雷达是一个全相参和全极化的系统,采用极化数字波束形成技术实现对干扰的空域抑制,采用脉冲压缩技术和瞬态极化目标识别技术实现对目标信号的正确分选。阐述了一种极化阵列制导雷达的系统设计方案,论述了在此系统中数字波束形成的实现方法,研究了一种全极化信号处理方法,并通过仿真实验分析了该雷达的抗干扰性能。提出的抗干扰方法结合了数字波束形成技术和极化信号处理技术的优点,增强了制导雷达对各种电子干扰的综合对抗能力,在系统实现上具有可行性。

This paper proposes a polarization phased array radar system on missiles to improve the electronic warfare performances of the guidance radars. The radar is a coherent and dual polarization system,in which the digital beam forming (DBF) is used to suppress the space interferences and the target signal is recognized through dual polarization pulse compression technology and instantaneous polarization detection technology. The system scheme of the polarization phased array radar is discussed,and the realizati...
