摘　　要：针对参差雷达脉冲信号分选这一信号分选领域的难题,在分析扩展关联法基本原理的基础上,建立了以脉冲到达时间和脉冲列重复周期为变量的函数。通过检测函数峰值位置,提取出不同重复周期的脉冲列和各脉冲到达时间,利用脉冲到达时间进行脉冲抽取,实现了交迭脉冲列分选。仿真结果表明该算法对固定、参差重复周期脉冲列都有较好的分选效果。To solve the problem of sorting stagger pulse series, a function is established with variables TOA and PRI based on the basic principle of the expanded association algorithm. By detecting the position of the function＇s peak value, PRI of pulse series and TOA of pulses in the series are obtained. According to TOA, the pulse series are picked up from the mixed pulse series to realize signal sorting. The simulation results show that this algorithm is effective in sorting pulse series with stable PRI and staggered PRI.
