| 摘 要： | 海冰分类是遥感监测领域中的重要应用之一，海冰分类的准确性对于评估海冰冰情、保证航海安全和开辟北极航道具有重要的意义。针对海冰分类问题，本文选用Sentinel-1遥感数据，结合纹理特征分析，提出了一种改进的SAR海冰分类方法。该方法选用灰度共生矩阵提取特征值，通过实验得到适宜用于海冰分类的多特征组合，在此基础上利用支持向量机开展SAR海冰类型的分类研究。实验结果表明，该方法可以实现对海冰SAR图像中一年冰、多年冰和海水3种类型识别，与传统的海冰分类方法神经网络和最大似然法相比较，使用SVM分类方法，结合纹理特征开展海冰类型监测是可行的，同时也表明多特征组合有利于提高SAR图像的分类精度，从而验证了本方法的有效性，为海冰分类提供了一种新思路。

| Abstract: | The classification of sea ice is one of the most important applications in the field of remote sensing monitoring, and its accuracy is of great significance in assessing the ice conditions, ensuring the safety of navigation and opening up the Arctic channel. In order to solve the sea ice classification problems, this paper proposed an improved SAR sea ice classification method, which used Sentinel-1 data and texture feature analysis. In this method, the gray level co-occurrence matrix (GLCM) was used to extract the eigenvalue, and the suitable of texture features for sea ice classification was obtained, then we used support vector machine to carried out sea ice classification. The experimental results showed that the proposed method can recognize three types of ice, which are first year ice, multiyear ice and open water. Compared with the traditional methods of Neural Net and Maximum Likelihood, it is feasible to use SVM classification method and texture feature to monitor sea ice type. It also showed that multi-feature is helpful to improve the classification accuracy of SAR image, which verifies the effectiveness of this method and provides a new idea for sea ice classification. |
