| 摘 要： | 针对个体辐射源识别困难的问题,提出了一种基于双谱分析的个体辐射源识别新方法.首先用双谱分析法提取信号的双谱对角切片,利用主成分分析法(PCA)从大量训练样本特征中挑选低维、低复杂度的特征矢量,并融合对分类具有显著贡献的辐射源属性参数作为识别特征矢量.最后采用势函数分类法实现雷达辐射源识别.仿真结果表明基于双谱的识别法能...

| Abstract: | With respect to specific emitter identification,a new identification approach for radar emitter based on bispectrum analysis is proposed.Diagonal slice features of bispectrum which adapts to process radar non-linearity signals are extracted,and principal analysis is utilized to extract low-dimensional feature vectors with low complexity from a large of training sample features.Moreover,emitter attribute parameters significant to identification are merged into the identification feature vector.At last,radar ... |
