| 摘要: |
| 目标高分辨一维距离像（High Resolution Range Profile,HRRP）中包含了丰富的目标尺寸、结构等目标特征，是进行空间目标身份识别的有效途径。但由于卫星宽带雷达实测数据获取难度大，前期相关研究多集中于基于HRRP的目标识别算法，结论也多是基于仿真数据和少量类别（几类）的前提下得到的，与工程应用实际情况有较大差距，工程指导意义有限。为解决这一问题，基于地基雷达获取的30类卫星目标的大量一维距离像实测数据，从识别正确率的角度对目标HRRP及其特征（组合）的可分性和在空间目标个体识别中的应用效果进行了量化分析，分析结果可为后续基于HRRP的空间目标个体识别技术研究和工程应用提供可靠依据。 |

| Abstract: |
| High resolution range profile(HRRP) which contains target features such as size and structure is an important basis for space target identity recognition.Howerver,the relevant researches before are focused on the target recognition algorithm based on HRRP,and the conclusions based on the situation of simulation data and small class number are not suitable for the engineering practice.In order to solve this problem,the effects of space target recognition based on HRRP and its features are analyzed based on the data of 30 kinds of space target which is measured by ground-based radars.The results can provide reference and basis for the research and engineering application of space target recognition. |
