Large Scale Interferometry over Filchner-Ronne Ice Shelf

ABSTRACT. The Filchner-Ronne Ice Shelf (FRIS) is the largest mass of floating ice, located to the east of the Antarctic Peninsula with an area of about 449,000 square kilometres.

Description
Summary:ABSTRACT. The Filchner-Ronne Ice Shelf (FRIS) is the largest mass of floating ice, located to the east of the Antarctic Peninsula with an area of about 449,000 square kilometres. The work presented here is part of the international ERS AO3 Vectra project. One objective is a high quality map of surface motion. We summarize some of the first results obtained by interferometric processing of more than 80 ERS single look complex (SLC) scenes, covering an area of approximately 140,000 square kilometres near the ice front, including a comparison with results of numerical model studies. Coherence is present over a time interval of up to 18 days. The INSAR processor was developed at the Institute of Navigation with the capability to handle large data volumes. Aspects of the mosaicking of SLC data sets will be discussed.
