摘要：

Sea ice charts are provided operationally by the Canadian Ice Service (CIS) for the convenience of people in high-latitude regions. Hence, approaches to ice-water discrimination are in demand. An approach is proposed in this paper, in which no manual interpretation is involved in the selection of training data. It is done based on the discrepancy of incidence angle dependence between sea ice and open water. This approach has been tested on five synthetic aperture radar (SAR) images from Envisat Advance SAR (ASAR). The validation shows that the approach works fairly well in identifying large areas of open water with an average accuracy of 92.97%.
