基于双谱特征的超宽带雷达人体目标识别
Ultra-wideband Radar Human Target Recognition Based on Bispectrum Feature
摘要
Abstract
In order to identify human targets when micro-Doppler features are not obvious,a method combi-ning diagonal fluctuation characteristic of echo bispectrum with distribution of strong scattering points is presented. Firstly,the bispectrum of static human targets is analyzed and diagonal fluctuation characteristic of echo bispectrum is extracted. Thus,characteristic dimension of bispectrum and feature redundancy are reduced. Secondly,to describe targets in different aspects,distribution feature of strong scattering points is combined with bispectrum and feature vector which is used to recognize targets is constructed. Finally,tar-gets recognition is realized by using Support Vector Machine( SVM) . Both simulation and measurement re-sults show that the proposed method can effectively recognize human target and human posture.关键词
