Target HRRP Length Estimation Based on Significant Energy Aggregation

Radar target length can be extracted from high resolution range profile (HRRP), which is one of important characteristics for radar aerial targets identification. In order to improve the precision and accuracy of target length extraction, a significant energy aggregation method for target length estimation from HRRP is proposed in this paper. And the key to this method is to extract the range bins that aggregate target significant energy in HRRP. Experimental results and analysis of measured data indicate that the proposed method can effectively extract the target length.
