Synthetic Aperture Radar (SAR) images are commonly used to monitor glacier flow velocity at Greenland Ice Sheet (GrIS). However, offset-tracking with SAR imagery in summer usually show poor quality because the rapid ice surface freezing-melting cycles contaminating backscattering characteristic, while optical less sensitive this phenomenon. In study, we combine Sentinel-1 and -2 create time series for Petermann glacier, located northern GrIS. Firstly, technique is employed acquire initial...
格陵兰冰盖流速监测对定量估算冰盖物质损失以及研究冰盖对全球变暖的响应具有重要意义。利用SAR影像强度信息进行偏移量追踪是目前冰川流速监测的主要方法。冰川表面散射特性的变化会导致SAR影像强度信息发生改变,导致影像匹配失相关,从而造成提取的流速场中存在大量错误与空洞。为了克服该问题,本文提出了一套基于Sentinel-1...
