基于集对分析的雷达信号分选算法

Radar Signal Sorting Method Based on Set Pair Analysis

随着新体制、新技术雷达的不断出现,雷达侦察接收机接收到的雷达信号更加密集和复杂,传统的分选方法已不能对其进行有效分选。将雷达脉冲信号与已知雷达的脉冲信号特征两两视为集对,应用集对分析算法,通过计算脉冲信号之间的关联度,实现信号分选。仿真结果表明,该算法不仅简单,易于编程,而且与传统分选算法相比,能实时、高效地实现密集和复杂信号环境下的信号分选任务。

With the new system and technique radars developing rapidly, the radar signals received by the radar ceiver are more intensive and complicated. Traditional radar signal sorting methods cant sort these signals effectively. A method u- sing set pair analysis is presented in this paper. Radar pulse and known characteristics of radar pulses were regarded as one set pair to achieve signal sorting by calculating the correlation of the pulse signal with set pair analysis algorithm. Simulation results indi- cate that the algorithm is simple, can be easily programmed. Intensive and complex signals can be sorted in real-time effectively with high-accuracy.
