摘　　要：研究了一种基于最小描述长度(MDL)原理的快速在线雷达脉冲信号聚类分选算法,该方法利用幅度或相位差异特征,实现对雷达脉冲数据向量的聚类分选处理。设计了基于MDL原理的在线信号分选算法流程,在每接收到一定数量雷达脉冲信号后,执行一次聚类分选处理;对算法流程中的每个处理模块进行了完备的运算量分析,为工程设计提供有效的理论指导;并对比分析了离线和在线算法的性能。仿真结果表明:在线算法的信号分选正确率与离线方法基本一致,具有很强的工程应用前景。The fast online radar signal deinterleaving algorithm based on minimum description length （ MDL} criterion is researched in this paper. Radar pulse signals is deinterleaved by using inner-pulse amplitude or phase modulation characteristics. Radar pulse signals are clustering sorted after receiving the amount of pulses, and the processing flow of online signal deinterleaving algorithm is designed based on MDL. The calculating quantity of each processing module in the algorithm flow is analyzed, and the performance of offline and online algorithm is contrasted. The result of simulation shows that the performance of online method is as the same as the offline method approximately, and the online deinterleaving algorithm is nice foreground in engineering application.
