RADARSAT SAR Sea Ice Motion [Kwok, R. and H. Stern]

Summary

The Canadian RADARSAT satellite collected 195 synthetic aperture radar (SAR) images of the SHEBA site November 1, 1997, and October 8, 1998 (roughly one image every 3-5 days). The C-band (5.3 GHz) RADARSAT SAR imaged a swath on the earth 460 km wide (in ScanSAR mode) with a pixel size of 50 m, unhampered by clouds or darkness. The satellite data were received and processed into imagery at the Alaska SAR Facility (ASF) in Fairbanks. Sequential pairs of images were then processed by the RADARSAT Geophysical Processor System (RGPS) at the Jet Propulsion Laboratory (JPL) in Pasadena to derive the motion of the sea ice on a 5-km grid by tracking common features in each pair of images. Thus we have a year-long record of the spatial pattern of ice motion and the radar backscatter in the vicinity of the SHEBA site.

The RADARSAT Geophysical Processor System (RGPS) created 184 ice motion products from 184 sequential pairs of RADARSAT SAR images of the SHEBA region.
