单脉冲末制导雷达舷外有源雷达诱饵检测研究

Study on outboard active radar decoy detection of monopulse terminal guidance radar

舷外有源雷达诱饵通过与舰船形成双目标非相干干扰,对单脉冲末制导雷达的角跟踪系统产生真正的角度欺骗,影响反舰导弹对舰船的可靠跟踪。单脉冲末制导雷达接收机输出信号在一定条件下近似为高斯分布,采用GLRT方法可以对舰船和诱饵进行检测。

The dual-objective non-coherent interference is formed by outboard active radar decoy and ship, which may generate the true angle deception to the angle tracking system of the monopulse terminal guidance radar, and affect antiship missile on re- liable tracking of the ships. The output signal of the monopulse terminal guidance radar receiver is approximate to Gaussian dis- tribution under a certain condition, so GLRT method can detect the ship and decoy.
