| 摘 要： | Lincoln实验室提出的SAR(synthetic aperture radar)ATR(automatic target recognition)算法由于其经典性而被广泛采用,该算法为三级结构模式,处于其中Prescreener级和Discriminator级之间的聚类算法对于检测算法整体性能有重要的影响,文中介绍了SAR ATR算法采用的常规聚类算法,分析了常规算法在聚类过程中存在的杂波干扰问题,针对问题在聚类前引入形态学操作方法,将待聚类图像中包含的孤立点删除而只保留团状分布的样本,从而消除了杂波点对聚类的干扰,基于实际SAR图像的聚类结果验证了应用形态学方法对提高聚类效果的有效性.

| Abstract: | AR(Synthetic Aperture Radar) ATR(Automatic Target Recognition) algorithm proposed by Lincoln Lab is widely used for its classic mode that is a three-stage framework.The clustering algorithm between Prescreener and Discriminator of SAR ATR algorithm is important for the performance of detection algorithm.This paper introduces the common clustering algorithm used in SAR ATR algorithm and analyzes its disadvantages of clutter disturbance.A morphologic method is proposed to be used before clustering that can delete the isolated pixels and save the pixel blobs in an image.It avoids the disturbance of clutter for clustering.The clustering results of an actual SAR image testify that the morphologic method is effective for improving clustering results. |
