HRRP自动目标识别方法综述

Radar high resolution range profile (HRRP) target automatic recognition is a hot research field in radar target recognition in recent years. Based on the research status of HRRP automatic recognition methods at home and abroad, firstly, two problems that need to be solved at present were pointed out: the recognition of non-cooperative targets and the acquisition of classified hyperplanes. Secondly, three focuses about the problems were proposed: research on SNR's mismatch, research on a small number of incomplete samples and research on classification hyperplane acquisition methods. Then the research ideas of each research focus were divided detailedly, including removal of noise components, feature extraction, support vectors, etc. and the the research status of each idea was summarized. Finally, the research status of the three focuses was summarized and the future development direction of the three focuses was pointed out.
