英文摘要：

The key of monitoring and detection sea ice is extracting the sea ice types.Extracting sea ice types exactly has important significance for evaluating sea ice condition and ensuring navigation and marine operation safety.In this paper,the polarimetric scattering characteristics of sea ice are extracted by using high-resolution and fullypolarimetric SAR imagery.By combining the binary-tree classification idea,a sea ice classification algorithm of high-resolution and fully-polarimetric SAR data is developed,enhancing the SAR classification accuracy of sea ice.Finally,we verify the reliability of this method by comparing with the traditional sea ice classification method.
