摘要 提出了一种对SAR图像中的椭圆形目标进行自动识别的综合方法。它利用SAR图像所具有的统计特性、CFAR检测对SAR图像进行预处理。根据中心椭圆算法构造椭圆并计算以此灰度占空比系数,采用马氏距离从背景中识别出目标。实际SAR图像实验结果表明了该方法的有效性。 A new method of ellipse target recognition for SAR images is proposed.The pretreatment of SAR images has been achieved by means of statistic characterization,CFAR detection.Making ellipse and computing its occupy ratio by using Central Ellipse algorithm.The target is recognized via M-distance finally.The validity of this method is proved by real SAR image.
