摘要 雷达目标识别的预处理工作是高分辨距离像领域中的重要组成部分,也是提高识别率的重点和难点。给出了一种结合信号统计特性的信号预处理方法,通过对高分辨距离像(highresolutionrangeprofiles,HRRP)的非线性变换作为特征,有效地拉大了异类目标信号之间的欧氏距离,从而提高了分类的识别率。基于ISAR雷达实测飞机数据的实验结果证明了该方法的有效性。 Pre-processing of radar target recognition with high-resolution range profiles（HRRPs） is a significant but difficult point in improving recognition performance. A new signal pre-processing method based on statistic features is proposed, which successfully increases the Euclidean distance among feature vectors of separate targets by a nonlinear transform of HRRPs, thus enhancing the recognition performance. Experimental results based on the ISAR radar airplane data demonstrate the improved performance with the proposed method.
