摘　　要：为了有效反电子侦察系统对舰载雷达脉冲信号的分选识别,从主动干扰侦察系统角度出发,研究了典型聚类方法的原理和特点,根据雷达脉冲数据密度特征,设计脉冲干扰信号对电子侦察系统进行干扰,造成雷达脉冲重复丢失,产生漏批现象,从而影响聚类结果,仿真分选结果验证干扰的有效性。In order to effectively distinguish and recognize shipborne radar pulse signals by anti-electronic reconnaissance system,the principles and characteristics of three typical clustering methods are studied from the perspective of active interference reconnaissance system.According to the characteristics of radar pulse data density,pulse interference signals are designed to interfere with electronic reconnaissance system,resulting in repeated loss of radar pulses and"missing batch"phenomenon,thus affecting the clustering results.Simulation sorting results verify the effectiveness of the interference.
