| 摘 要： | 提出了基于距离像序列的空间目标识别算法,首先对距离像序列进行小波消噪,然后应用RELAX算法提取出目标强散射中心的位置和幅度,根据高于幅度门限的强散射中心的位置来确定目标径向长度,最后根据目标径向长度序列的均值和标准差对三轴稳定卫星、自旋稳定卫星和碎片进行分类识别。计算机仿真结果表明,该算法取得了比较好的识别效果。

| Abstract: | A space target recognition algorithm based on range profile sequence is put forward in this paper.Firstly wavelet denoise of range profile sequence is carried out,and location and amplitude of target strong scatter centers are extracted using RELAX algorithm.Then target radial length is obtained according to location of strong scatter centers whose amplitude is higher than amplitude-threshold.Finally three-axis stabilization satellite,spin stabilization satellite and debris are recognized according to mean and standard deviation of target radial length sequence.Computer simulation shows this algorithm can achieve good recognition effect. |
