高分辨雷达目标识别可以提供目标更多的信息 ,是地面雷达技术发展方向 ,基于高分辨距离像的特征提取和识别是比较现实可行的方法。该文首先分析了一维距离像的产生 ,在此基础上 ,综合了几种一维距离像的特征提取方法和分类识别方法 ,讨论了方位角变化对距离像的影响 。

Target recognition for high range resolution radar (HRR) is of great importance. Basing on the analysis of property of one dimension high range resolution profile (HRRP), a theoretical analysis of the synthesized echoes in a range cell is presented in this paper. The geometric relationship between 1D HRRP and aspect angle of a target is established. The problem of robustness of the method is also analyzed.
