摘　　要：针对传统扩展关联分选法在分选时效率低、对复杂调制PRI信号分选性能差的问题,提出了一种基于扩展关联分选的改进算法。基于脉冲位置相关性建立对应三维向量矩阵,提高提取准PRI的准确性,同时提出"分步逐级"的策略,从而确保复杂调制PRI信号的分选性能。仿真结果表明该算法具有可行性,分选性能相较于传统基于PRI分选的方法有很大的提高。A improvement algorithm based on expanded association algorithm is proposed to deal with the problem that the traditional expanded association algorithm is of low efficiency when sorting and of poor sorting performance to sort the signal of PRI complex modulated.A 3-d matrix is established based on the pulse position relativity,and it can improve the veracity of quasi-PRI extraction,and present a strategy of“step-by-step”to insure the sorting performance of PRI complex modulated.The simulation result proves that the algorithm of sorting is feasible,and the sorting performance is greatly improved compared with the traditional algorithm based on PRI.
