针对实际应用中电子战设备对雷达信号分选的实时性要求，在分析了序列差直方图算法和多核DSP任务并行模式的基础上，设计了基于TMS320C6678的八核DSP雷达信号分选电路，对密集的雷达信号进行分选。实验结果表明：该电路可对常规雷达信号实现快速分选，并且分选效果良好，系统可靠性高。

The paper presents an improved method for the deinterleaving of radar signals, based on a time of arrival analysis and the use of the sequential difference histogram (SDIF) for determining the pulse repetition interval (PRI). The optimal detection threshold in the SDIF histogram is derived, which greatly contributes to the efficiency of the algorithm. The algorithm is applied to classic, frequency-agile and staggered PRI radar signals. It is shown that the new method is very successful in high-pulse-density radar environments and for complex signal types. Special attention is given to an application of this method to the multiple-parameter deinterleaving algorithm.

 为了能够从同时存在常规PRI信号和复杂PRI信号并带有脉冲信号干扰或丢失的环境中正确分选出雷达信号，本文提出了一种序列差值直方图法（SDIF）与修正PRI变换法相结合的雷达信号分选方法，经过matlab仿真验证，该方法有着很好的分选效果。
