Sea Ice Displacement from SEASAT Synthetic Aperture Radar,

Abstract

Images obtained by a synthetic aperture radar on SEASAT have been used to measure sea ice displacements over a three day interval in October 1978. The data points lie roughly along a line and are quite dense--about 2 km apart--over a distance of 863 km. The displacements are about twenty kilometers. Displacement errors grow with distance from shore becoming as large as 3 km. The graph of displacement versus distance has occasional discontinuities of several kilometers. Displacement discontinuities are accurate to + or - 0.07 km along track and 3% of their magnitude across track.
