In order to solve the problem that the results of automatic target recognition of SAR images using exist some methods are still not satisfactory,three methods are proposed in this paper for automatic target recognition of SAR images,that is,target recognition using intensity features,target recognition using grid features,and target recognition using template features.
针对已有的SAR图像自动目标识别方法效果不太好的问题,提出了SAR图像的自动目标识别三种方法,即采用灰度特征的目标识别,采用栅格特征的目标识别,和采用模版特征的目标识别。
