复杂电磁环境下雷达信号分选技术

Radar Signal Sorting Technology in Complex Electromagnetic Environment

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。

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.
