摘　　要：为了有效反电子战侦察对雷达信号的分选识别,从主动反侦察角度出发,分析了CDIF、PRI变换信号分选方法的特点,论证了抗重频分选的可行性,提出了利用一定规则设计的重频组合干扰脉冲扰乱雷达脉冲间存在的规律性,破坏分选算法对雷达信号的统计属性;实验表明:随机加入干扰脉冲很难奏效,干扰脉冲需要按照一定规则设计,才能有效实现抗重频分选,达到反侦察效果。In order to protect radar pulse repetition interval from sorting, from the view of offensive counter reconnaissance, the characteristics of CDIF and PRI transform algorithm were analyzed, and the possibility of anti-sorting was discussed. Using combined rule jamming pulses to disrupt the radar pulses＇ regularity and destroy the statistical performance of sorting algorithm were also proposed. The simulation indicates that jamming pulses should be designed by rules or they could not work effectively.
