摘　　要：针对电子战所面临的高密度,占空比大,脉冲重叠丢失率高的信号环境,构建了一个实时的脉冲信号预分选系统,改进了基于概率统计的分选算法,并提出一个剔除TOA倍数及加和关系的算法,通过试验证明了该系统和算法的可行性。通过硬件电路进行了具体实现,该系统能实时的对雷达脉冲序列进行分选,并在密集的信号环境下具有良好的分选正确率。A real-time signal sorting system and an improved sorting algorithm based on the probability statistics is introduced. It is for the special radar signal environment of high pulse-density and high pulse-losing probability in electronic warfsre. The feasibility of this sorting system and algorithm is verified through lots of experiments. By designing the hardware circuits, the signal sorting system is realized. It performs well for duplex requirement of high-accuracy and real-time processing in high pulse-density environment.
