摘　　要：高分辨距离像(HRRP)是宽带雷达获取的目标散射点子回波沿雷达视线方向的投影矢量和。它能够提供目标的距离向几何结构和材料质地信息,且易于获取和处理,因此国内外许多学者将研究重点集中在基于HRRP的目标识别技术。本文简介了基于HRRP的目标识别系统模型,总结了HRRP姿态敏感性等关键问题及其解决途径,综述了基于HRRP目标识别的特征提取、分类器设计两项关键技术的研究现状,讨论了其未来发展方向。High resolution range profile(HRRP) is the projection vector sum of target scattering point echoes acquired by wide-band radar along the direction of radar line-of-sight(LOS).It can provide the range-direction geometric structure and material texture information of the target.Because of the ease of acquisition and data processing,many scholars home and abroad concentrate on target recognition technology based on HRRP.This paper firstly introduces a target recognition system model based on HRRP.Then,key problems such as HRRP attitude sensitivity and the solutions are summarized.An overview is given on the present research status of feature extraction and classifier design,which are two critical techniques in this field.Finally,several future research directions in this field are discussed.
