Abstract
This paper presents some results of ONR/Navy sponsored research on remote sensing of sea ice. Progress in determining radar backscatter properties of various types of sea ice over primarily winter conditions is shown. Results of effects of snow cover on backscatter properties of sea ice are included. X- and L-band synthetic aperture radar imagery of sea ice are compared for selection of the optimum frequency for sea ice detection and classification of ice types. To aid in the selection of an appropriate SAR resolution for use on sea ice, SAR imagery equivalent to the 25 meter SEASAT-A resolution is successively degraded to 50 meter and 100 meter resolutions and the results shown for purposes of comparison. Finally, sea ice data from a four frequency passive microwave radiometer are displayed. The paper concludes with an outline of ONR’s future plans for sea ice remote sensing.
