基于GUI的雷达信号抗分选性能评估系统

为适应现代战场对雷达信号低截获性能的需求,设计了雷达信号抗分选性能的评估系统,分析了雷达信号分选的常用算法包括累积差直方图(CDIF)和序列差直方图(SDIF)。模拟雷达信号环境,将设计的同步频率捷变信号、PRI抖动信号和PRI调制信号经过分选评估系统,计算分选结果的准确率、分选时间等,通过以上几个因素的加权提出了信号复杂度的计算方法。对比信号之间的复杂度系数,达到定量评估雷达信号抗分选性能的目的,并为设计具有低截获性能的雷达信号提供参考。运行结果表明,软件运行效果好,可视化程度高,使用方便快捷。

Estimation system of radar signals＇ anti de-interleaving ability based on GUI

In order to adapt to the modern war,the radar signal should have the priority of low possibility of intercept.This system for the purpose of evaluating the LPI ability of the radar signals is designed.Analysis the de-interleaving methods include CDIF and SDIF,analog the environment of ESM,then calculate the complexity of the signals through the time-using,and the precision of the results.We can evaluate the performance of the signals through comparing the complexity of them.The software runs well and all procedure is integrated in a graphic user interface in order for demonstrate.
