高密度复杂信号环境下的信号分选处理技术是新一代雷达截获接收机信号处理的关键技术，也是雷达截获领域一个亟待解决的问题。文中讨论基于脉冲重复间隔(PRI)的脉冲分选算法，深入分析了基于直方图统计算法和PRI变换算法的优缺点，并对算法进行计算机仿真。最后针对这两种算法的优缺点提出一种综合的分选算法。

Sorting of radar pulses in high density signal e nvironment is a key technology of signal processing for new generation radar int ercept system. In this paper, methods of sorting of radar pulses based on PRI ar e discussed. The histogram statistics algorithms and PRI transfer algorithm are analyzed and simulated. Finally, a synthesis method is proposed.
