| 摘 要： | 基于高分辨距离像(HRRP)的舰船目标识别问题,提出了一种基于高阶谱特征的舰船目标识别方法。在对舰船目标HRRP特性分析的基础上,首先利用姿态角进行方位约束筛选,然后通过高阶谱特征结合欧氏距离测度最近邻分类器进行识别匹配。通过10类军民船目标的实测数据进行测试,验证结果表明该方法在舰船目标识别领域具有很好的应用前景。

| Abstract: | A method based on high-order spectra is proposed for ship target recognition.Firstly,templates are separated by ship attitude angle estimated in radar track.Then,high-order spectra feature is extracted from high resolution range profile,and combined with the Euclidean distance based nearest neighbor classification.The result of experiment with the actual measured data of 10 ship targets indicates that the proposed method is efficient and very useful in ship target classification. |
