Study on microwave scattering of rough sea surface based on the corrected TS model

The high-accuracy retrieval of sea remote sensing information, such as wind field, wave height and Permittivity, is determined by the microwave scattering model at the sea surface. Thus it is meaningful to study the accurate microwave scattering characteristic of rough sea surface. Based on the current Two-Scale model, this paper modifies the model of microwave scattering from three aspects: the correction of Non-linear anisotropic sea spectrum, the correction of the joint probability density of the Non-linear anisotropic sea-surface slope and the correction of shadowing effect. It is shown by simulation that the data obtained from corrected Two-Scale model is much closer to the real experimental data than from the conventional Two-Scale model.
