摘　　要：基于电子对抗等非协作电子环境,针对抖动脉冲重复周期(Pulse Repetition Interval,PRI)信号,在SDIF的基础上提出了一种改进的算法。该方法主要从潜在PRI的估计和序列检索方法入手,提出了一种潜在PRI估计值的筛选方法和一种新的序列检索方法,有效提高了雷达脉冲信号的分选准确率,并降低了整个分选过程的计算量。仿真结果验证了该方法的有效性。Based on the non-cooperative electronic environment,an improved SDIF algorithm is proposed in this paper to deal with the jitter of the signals＇ pulse repetition interval（PRI）. A screening method of potential PRI and a new method of sequence retrieval are presented in this paper.The improved method can effectively improve the sorting accuracy of the radar pulse signal and reduce the calculation amount of the whole sorting process. Simulation results verify the effectiveness of the proposed method.
