Demonstration of X-Band SAR Interferometry over Baltic Fast Ice

Övrigt konferensbidrag, 2013

This study utilizes X-band SAR images acquired by the Cosmo-SkyMed satellite constellation to map fast ice deformation at high spatial resolution. Two interferometric acquisitions were performed in the middle of the ice season in 2012 and with a temporal baseline of 24 hours. The first interferogram reveals deformation of the fast ice which is being forced by the ramming drift ice. The drift ice moved towards the fast ice with up to 600 m based on phase correlation measurements. The second interferogram shows a rather low fringe rate over the fast ice with fringes being aligned along the coastline. Emerging cracks are easily identified with the associated phase discontinuities. It is also observed that the backscatter and coherence levels are connected in certain regions.
