摘　　要：随着雷达技术的快速发展和军事应用的迫切需求,目标识别问题日益受到重视,利用高分辨率雷达一维距离像进行目标识别成为雷达和信号处理领域的一个研究热点。雷达目标一维距离像能够反映目标形状及结构特征,而且易于获取,迄今为止采用一维距离像进行非合作目标识别已经取得了丰富的研究成果。总结了近年来研究的基于目标一维距离像的特征提取方法、分类方法和联合跟踪与识别方法,分析了当前研究中亟需解决的关键问题,探讨了这些问题的可能解决思路和发展方向。Radar target recognition is increasingly important with the development of radar techniques and the urgent military requirements. The research on radar target recognition using one-dimensional high range resolution profiles is a popular area in the radar and signal processing community. The range profiles can not on ly provide the information on shape and structure of the target but also be obtained easily. So far extensive re- search work has already been made in the field of non-cooperazive target recognition using the range profiles. The feature extraction algorithm, classification algorithm and joint tracking and recognition algorithm based on the radar range profiles are summarized. Finally, the still open problems are discussed and some suggestions on the solutions and research trends are proposed.
