Estimation of Equivalent Deformed Ice Thickness from Baltic Sea Ice
FIMR has been utilizing the Radarsat-1 ScanSAR data inoperational sea ice monitoring for several years. The surfacescattering dominates the backscattering at C-band, but itis still possible to estimate ice thickness based on this surfaceroughness visible in SAR data in some areas of the Baltic Sea,b...
