摘　　要：针对雷达脉冲序列的主要特点,利用TOA(脉冲到达时间)差值矩阵探索PRI(脉冲重复间隔)的识别问题。设计了一种新方法,首先由TOA序列求出TOA差值矩阵,再求出TOA差值矩阵的逆矩阵,分析TOA差值矩阵逆矩阵的特殊结构,得到PRI的识别结果。通过研究重频固定、脉冲丢失和重频参差三种情况下的PRI识别问题,说明了该方法用于雷达脉冲序列PRI识别的可行性。Aiming at the main trait of radar purse sequences, it explores PRI （Pulse Repetition Interval） recognition by means of TOA（Time of Arrival） difference matrix. A new method is designed, firstly obtains TOA difference matrix from TOA series, then solves the inverse matrix, analyzes the TOA difference matrix＇s special structure, and finally achieves the results of PRI recognition. The study is performed among const repetition frequency, pulse dismiss and staggered frequency, the feasibility of this method is testified.
