Abstract: Based on the analysis of Migration Through Resolution Cell(MTRC) of high peaks in HRRP of cone reentry vehicle,the smoothing of migration of high peaks and fluctuation of amplitude in High-Resolution Range Profiles(HRRP)is obtained by multi-scale Harr wavelet transform which makes the correlation between changing HRRP more stable and improved in wider Radar Line Of Sight(RLOS).Using maximum correlative matching method,higher recognization rate of simulated targets and enhanced correlation of real data are obtained.
