Abstract :
For automated interpretation of the sea ice SAR data, the change in backscatter level due to the incidence angle variation should be taken into account. We have studied the statistics of the Radarsat ScanSAR Narrow data for sea ice, and developed an iterative algorithm for normalizing the data for automated interpretation of it.
