单脉冲导引头对多干扰源的角分辨

Angle Resolution of Multiple Jammers for Monopulse Seeker

当多个噪声调频干扰同时进入单脉冲导引头主波束内时 ,导引头对干扰源的角度分辨是非常困难的。本文主要研究了导引头单脉冲接收机对宽带噪声调频干扰源的响应 ,分析了当单脉冲主波束内存在多个噪声调频干扰源时 ,导引头指向角的跟踪规律 ,并重点讨论了一种用聚类来提取角信息的方法 ,最后仿真证实了该方法的正确性和有效性。

It is very difficult to resolve multiple jammers in the mainlobe of a monopulse seeker. This paper discusses the response of a monopulse seeker to noise frequency modulation jammer. This variety of response types is analyzed when multiple jammers appear in the mainlobe of monopulse seeker. The instantaneous angles of jammers can be resolved by a clustering method. The method is verified with the results of computer simulation.
