在极地海域航行需要特别注意海冰状况，因为这是破冰船打破流冰或坚冰的主要障碍，使船只能够继续前进。遥感图像的进步为分类和识别各种特征，包括不同类型的海冰提供了有效手段。因此，它可以节省燃料和时间的整个航程，特别是当流冰或固定冰成为障碍的破冰船。在这项研究中，作者利用Radarsat-2的高分辨率合成孔径雷达（SAR）图像的潜在用途，以确定海冰条件，为2012年12月中国第29次南极研究考察期间的中国破冰船（雪龙号）的精确导航。从水平发射和水平接收偏振图像上的固定冰的不同功能被确定。当时雪龙号船上的一位专家证人证实了合成孔径雷达图像用于精确导航的潜在用途。最后的航行路线验证了我们对雪龙船的快冰和航行的分析。卸货位置的预测区域也被发现与最终航行路线后的实际船舶卸货位置匹配良好。
Navigation in polar sea regions requires special attention to the sea ice condition because it is a major barrier for an icebreaker to break the drift ice or fast ice, allowing the vessel to keep moving forward. The advancement of remote sensing imagery provides an effective means to classify and identify various features, including different types of sea ice. Hence, it permits fuel and time saving for the entire voyage, especially when drift ice or fast ice becomes a barrier for the icebreaker. In this study, the authors exploit the potential usage of high-resolution synthetic aperture radar (SAR) imageries from Radarsat-2 to identify sea ice conditions for precise navigation of China’s icebreaker vessel (Xuelong) during the 29th Chinese Antarctic Research Expedition in December 2012. Different features on the fast ice were identified from horizontal-transmit and horizontal-receive polarized imagery. The potential usage of SAR imagery for precise navigation was confirmed by an expert witness on the Xuelong vessel at that time. The final voyage route has validated our analysis of fast ice and navigation of the Xuelong vessel. The predicted regions for unloading locations were also found to be matching well with the actual vessel unloading locations after the final voyage route.
