Comparison of Measurements and Theory for Backscatter from Bare and Snow-covered Saline Ice
C-band backscatter measurements were made on artificially grown sea ice at the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) during the winters of 1987-1988 and 1988-1989. These measurements were made on smooth, rough, and snow-covered saline ice. The measured 0° (0) of smooth s...
