A Frame Segmentation Method for Radar HRRPs Based on Subspaee Model
摘要
Abstract
Principle component analysis and probabilistic principle component analysis models have been successfully used for radar HRRP target recognition.Traditional statistical modeling approaches segmented continuous radar HRRPs into several frames by equal interval partition method.A frame segmentation method based on subspace model is presented in this paper.Firstly, radar HRRPs are segmented into some subframes.Then the subspace angle and mean Euclidian distance between adjacent subframes are computed as a merging measurement.Finally, the adjacent subframes which have the minimum measurement are merged iteratively to finish the frame segmentation.The experiments based on the measured data obtain fewer frame numbers and higher recognition accuracy.关键词
