Abstract : Investigation of radar discrimination of sea ice is presented. Radar scatterometer data at 75 and 2.25 cm wavelength obtained from NASA Earth Resources Aircraft Program Mission 126 were analyzed. The mission was conducted in April, 1970, off the coast of Point Barrow, Alaska. The scatterometer data were separated into seven different categories of sea ice. Sea ice was categorized according to thickness and age. The radar scattering from sea ice is compared for different sea ice types. An analytical theory of scatter from sea ice was developed and is presented. (Modified author abstract)
