雷达目标一维距离像识别方法研究

提出了一种基于小波包分析和二叉树支持向量机相结合的雷达目标一维距离像识别方法.该方法充分利用了小波包对信号的时频分解和支持向量机在小样本分类中的优势,可以改善目标的特征稳定性,提高识别性能.通过采用聚类分析中的均值距离来生成二叉树,将分类器分布在各个节点上,构成了多类支持向量机,减少了分类器数量和重复训练样本的数量.对...

Research into The One-D Range Profiles Recognition Method of Radar Target

This paper presents a new one-D range profiles recognition method of radar target based on combining wavelet packet analysis(WPA) and the binary tree support vector machine(SVM). The method adequately uses the time-frequency analysis of WPA to signals and the advantage of SVM in the small-sample classification,which can improve the feature stability of targets and raise the recognition performance.This paper creates the binary tree by using the distance average in clustering analysis,distributes classifiers...
