摘　　要：重频分选方法中,由于序列差值直方图法(SDIF)对PRI抖动的雷达脉冲信号的分选能力差,而PRI变换法可以分选PRI抖动的雷达脉冲信号,但是运算量太大,难以实现实时分选。对SDIF算法进行了改进,采用交叠PRI箱的方法进行直方图的统计,使得改进后的SDIF在运算量增加不多的情况下,可以实时较好地分选PRI抖动量在10%以内的雷达脉冲信号。Among the current PRI sorting algorithms,the sequential difference histogram algorithm（SDIF） can’t deinterleave the radar signals with PRI jitter perfectly,while the PRI transform algorithm can deinterleave the PRI jittered radar signals but can’t realize in real time due to its huge computing cost.Therefore,the SDIF algorithm is improved by using overlapped PRI bins in histogram statistics.The im-proved SDIF algorithm doesn’t increase the amount of calculation a lot with respect to the original SDIF al-gorithm,and can well deinterleave the PRI jittered radar signals with jitter quantity within 10%.
