无源雷达中的直达波抑制方法

Method of Restraining Direct-arrival Wave in Passive Radar

对基于外辐射源的无源雷达系统中的直达波抑制方法进行了研究,采用相控阵雷达的自适应技术,通过加权向量调整从而在直达波干扰方向上产生零陷来抑制其干扰。通过仿真验证了算法的可行性,并对采用不同数量零陷的情况进行了仿真。

This paper studies the method of restraining direct-arrival wave of passive radar based on outside radiation source,which adopts the adaptive technique of phased array radar,generates zero failing in the direction of direct-arrive wave to restrain the jamming by adjusting weighted vector. Through simulation,This paper verifies the the feasibility of the algorithm,and simulates it in the condition of applying different number of zero failing.
