Abstract
Electromagnetic emission and scattering models use the sea surface spectrum or its statistics to model the surface roughness. However, in some cases it is desirable to apply the model over a surface height function directly, or to include other effects. The technique described consists of the numerical generation a random surface whose directional spectrum corresponds to that of a wind-driven sea surface, including or not swell waves, and eventually perturbed by rain. The time- dependence is introduced taking into account the deep-water or shallow-water dispersion relationships. Finally, foam patches are distributed over the sea surface according to the surface slopes and taking into account the foam statistical distribution and its extinction time. This moving sea surface generator can be easily applied to various remote sensing applications as emission and monostatic or bistatic scattering including the effect of the footprint size, and properly selecting the lower and upper cut-off wavenumbers, the impact of different spectra, swell, fetch, rain effects etc can be studied.
