摘要：
This paper deals with the simulations of scattering by the sea surface using Two-Scale Model (TSM) and the realistic unified sea spectrum in various bistatic configurations. After a brief theoretical presentation, our numerical results ( scattering matrix coefficients) are compared with measured data, with a semi-empirical model (CMOD5) and with other analytical models (Small Slope Approximation) in backscattering configuration. Then, we study the influence of sea parameters (wind speed and wind direction) upon the co- and cross-polarization signature in various bistatic configurations. Finally, we present the simulation of the signal received by an observer above the sea when a plane incident wave impinges on the ocean surface.
