In this paper, a 2-dimensional scattering model for sea ice based on the Finite Element Method (FEM) is presented. The scattering problem is formulated following a physics-separate strategy. The wave in the air domain is expressed by the scattered field formulation, while the wave in the sea ice domain is expressed by the total field formulation. The two separate physics and formulations are coupled...
In this study, we investigate the influence of Arctic sea ice surface roughness on full polarimetric C-band SAR features in the late summer season. Surface roughness measured from a helicopter-borne laser altimeter is compared to 14 individual SAR features holding a documented theoretical or empirical relation to surface roughness. Three C-band Radarsat-2 SAR scenes, covering a study area with both...
