Abstract

Abstract We used a coherent radar depth sounder operating at 150MHz to collect ice thickness data on outlet glaciers in northwestern Greenland. The radar data were collected in conjunction with laser surface elevation measurements and were tagged with GPS information for accurate geolocation. The radar signals were corrupted by multiple echoes between the aircraft and the ice surface, as well as between the ice surface and the ice-bedrock interface. We applied the homomorphic deconvolution technique to remove multiple echoes successfully and have identified the grounding line of a long ice shelf in northwestern Greenland.

格陵兰冰川出口的机载无线电回波测深

利用150MHz频率的相干雷达测深仪采集了格陵兰岛西北部出海口冰川的冰厚数据。雷达数据与激光地面高程测量一起收集，并使用GPS信息进行精确的地理定位。雷达信号被飞机与冰面之间，以及冰面与冰基岩界面之间的多重回波干扰。我们应用同态反褶积技术成功地去除了多次回波，并在格陵兰岛西北部的一个长冰架上识别出了接地线。

期刊介绍： The International Journal of Remote Sensing ( IJRS) is concerned with the theory, science and technology of remote sensing and novel applications of remotely sensed data. The journal’s focus includes remote sensing of the atmosphere, biosphere, cryosphere and the terrestrial earth, as well as human modifications to the earth system. Principal topics include: • Remotely sensed data collection, analysis, interpretation and display. • Surveying from space, air, water and ground platforms. • Imaging and related sensors. • Image processing. • Use of remotely sensed data. • Economic surveys and cost-benefit analyses. • Drones Section: Remote sensing with unmanned aerial systems (UASs, also known as unmanned aerial vehicles (UAVs), or drones).
