Research on Electromagnetic Scattering Properties from Complex Ocean Surface Based on Sea Water Permittivity Model
Abstract— The ocean surface electromagnetic scattering properties have important applications in marine environmental monitoring and detection of target on the sea. The bistatic specular scattering from ocean surface plays a major role in the coupling fields of target and ocean surface. Based on the satellite data of ocean salinity and temperature at the Western Pacific and Southeast coast, the accurate model is built to calculate the permittivity of sea water at different sea areas with foams. The relationships between the foam coverage and air-sea temperature difference and wind speed are analyzed. Based on the modified two-scale model and VRT(vector radiative transfer) theory, the electromagnetic scattering properties from ocean surface with foams at different sea areas are analyzed by using the volume-surface composite model. To make the scattering model conform better to the practice, the cut-off wavenumber at actual wind speed and frequency of incident wave is considered. Then the impacts of foam coverage, wind speed and frequency of incident wave on Brewster effect of ocean surface at different sea areas are further analyzed. The producing mechanism and changing rules of ocean surface Brewster are summarized and analyzed. The research results have important values in military and civil fields.
