摘要
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 foward. 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 and time saving for the entire voyage especially when drift ice or fast ice becomes a barrier for the icebreaker in this study we explore the potential usage of high-resolution synthetic aperture radar (SAR) imageries from Radarsat-2 to identity sea ice conditions for precise navigation of China's icebreaker vesel (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 iceland navigation of the Xuelong vessel. The predicted regions unloading locations were also found to be matching well with the actual vessel unloading locations after the final voyage route.
