The HH-backscatter signals have a good correlation with ice thickness, while HV return signals correlate better with fresh snow depth [18]. Additionally, depending on the polarization and ice cover types, the radar backscatter returned from freshwater ice covers is significantly influenced by the incidence angle of the system [22]. In co-polarizations (i.e., HH and VV), the radar backscatter has a negative relationship with incidence angle over a range from 20 to 60 degrees. For example, the ice class consisting of crushed and broken plates of ice and snow ice with 3–5 cm of snow yields the highest backscatter values at all incident angles.
