Simulation study on polarimetric microwave emission of ocean surface: model comparison and analysis

There are a few polarimetric emissivity models derived from solving ocean surface electromagnetic boundary value problem theoretically. In this paper, the full Stokes parameters of ocean surface emission simulated by three emissivity models at various ocean state were reviewed and inter-comparisons of the results from numerical simulation are carried out in detail, the effects of wave spectrums on the ocean surface emissivities were evaluated. The simulated four Stokes parameters of emission were compared with those by experimental formulations derived from airborne or spaceborne microwave radiometers.
