摘要 在分析锥体类弹头目标的高分辨距离像(HRRP)强散射点越距离单元走动的基础上,通过小波多尺度分解,平滑了HRRP中强峰值的位移和幅度的起伏,使得HRRP的相似性在较大方位角范围内得到稳定和提高。通过仿真和实测数据,使用最大相关匹配法,得到了较高的识别率和相关性。 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.
