摘要
针对雷达辐射源信号新特征选取问题,提出基于多元集对分析的熵特征评价方法.根据雷达辐射源信号香农熵、近似熵和范数熵特征的识别率、稳定性、灵敏性、时间复杂度和适用范围设计评价指标,采用多元集对分析对指标体系评价.仿真实验结果表明,多元集对分析能适应对不同属性重要度的要求,实现对雷达辐射源信号熵特征的评价,对雷达辐射源信号新特征选取有一定指导作用.
Abstract
Aiming at the problem of new feature selection for Radar Emitter Signals,a feature evaluation method of Radar Emitter Signals entropy feature based on Set Pair Analysis (SPA) is put forward.On the basis of the proposed feature evaluation index of Shannon entropy,approximate entropy,norm entropy feature of radar emitter signals,this method evaluates feature index through combining with set pair analysis.Experimental results show that set pair analysis can adapt the different demand of property importance and achieve better entropy feature evaluation of radar emitter signals,so this method have some directive function for the new feature selection of radar emitter signals.
