Sea ice detection using Ku-band radar onboard GPM satellite

The method for automatic sea ice detection by DPR data is suggested. The method is based on the analysis of the shape of normalized radar cross section dependence on the incidence angle. For refinement of ice position along the track one dimensional Canny edge detection procedure is applied. The data for winter 2016 were processed for the Sea of Okhotsk. The algorithm was validated using the radiometer data.
