复杂电磁环境下雷达信号分选技术

摘要

Based on the characters of pulse description word and several algorithms of PRI deinterleaving of radar pulses, an utilizable method is presented in engineering. This algorithm is based on a combination of a number of pulse batches based on PDW predeinterleaving and PRI deinterleaving . Firstly deinterleaving pulses are pre-sorted based on characters of pulses param-eters, and then deinterleaving pulse batches are sorted based on SDIF. At last signal parameters are analyzed and radar signals are recognized. By simulation, this method is correct.%在分析PDW各参数特点以及几种常用的脉冲串PRI分选算法的基础上，提出一种工程上较为实用的雷达信号分选的方法。该方法采用PDW预分选聚类和PRI主分选相结合的方法，首先根据PDW参数的特点进行预分选聚类，接着进行基于SDIF的信号主分选，最后对分选后的信号进行参数分析和辐射源确认。通过仿真算法验证，该方法是正确的。
