Combination of SAR and Radar Altimeter Data: Lambert Glacier/Amery Ice Shelf

Abstract

It has been noted previously that a maximum of information can be obtained from a combination of data from two sources, elevation and backscatter data (see for instance, section F.10). The maps of Lambert Glacier / Amery Ice Shelf presented here are examples of such a data combination; they are based on ERS-1/2 radar altimeter data and SAR data from the Canadian RADARSAT (Antarctic Mission). During the Antarctic Mission, the SAR sensor aboard RADARSAT was rotated such that it looked toward the South Pole — hence it covered the area that had been a gap in coverage in altimeter and SAR data from previous satellite missions. There were two Antarctic Missions, data here stem from the first Antarctic Imaging Campaign, which lasted from 9 September to 20 October 1997.
