This paper presents investigations on a one year time series of crossing orbit differential interferometry SAR acquisitions with a 1-, 5-and 6-days temporal baseline. The conditions for crossing orbit in-terferometry are briefly discussed as the requirement of a common ground spectrum has to be satisfied. The uniquely short revisit times give the(More)
Although sea ice thickness is not directly measured by means of radar sensors, its magnitude and variations are to a certain degree reflected by the sea ice surface characteristics. Establishing simple but robust empirical relationships between sea ice surface properties and SAR signatures is an alternative to a much more complex theoretical microwave(More)
Polarimetric SAR data may form a promising tool for monitoring thin sea ice thickness from space. During the Russian-German Transdrift XIII expedition in the Lena delta area in the Russian Arctic in May/April 2008, data sets of TerraSAR-X data in HH-VV Dual-Pol Strip Map mode, as well as coincident helicopter-borne sea ice thickness profiles could(More)
In this paper, we explore the capabilities of an algorithm for ice type classification. Our main motivation and exemplary application was the recent incident of the research vessel Akademik Shokalskiy, which was trapped in pack ice for about two weeks. Strong winds had driven ice floes into a bay, forming an area of pack ice, blocking the ship's(More)
This paper presents the processing of TanDEM-X acquisitions for the monitoring of the topography of the Petermann ice island. In this particular case the area under study is continuously moving and the acquisition geometry is changing, so the processing of the iceberg's DEMs is challenging and additional effects are to be considered. The SAR processing(More)
