A New Feature Extraction Method Using the Amplitude Fluctuation Property of Target HRRPs for Radar Automatic Target Recognition

DU Lan,LIU Hong-wei,BAO Zheng,ZHANG Jun-ying(National Lab.of Radar Signal Processing,Xidian University,Xi'an,Shaanxi 7100 71,China)  
Due to the aspect sensitivity of high-resolution range profile (HRRP),tradition al radar HRRP target recognition methods usually use average profile within some aspect region as aspect template.Actually,the amplitude fluctuation property of HRRPs also represents some feature information of target.According to the scatt ering center model,a new feature extraction method using the amplitude fluctuati on property of HRRPs is proposed in this paper.The weighted HRRP extracted by th e new method can represent the scatterer distribution in every range cell,thereb y it can describe the scattering property of target better.The experimental resu lts based on the measured data show that the new feature extraction method can i mprove recognition performances greatly.
