Abstract : The aim of this work is to study the impacts of the oil spills on the electromagnetic scattering of the ocean sur- faces in bistatic and monostatic configurations. Therefore, in this paper, we will study the influence of the pollut- ants (oil spills) on the physical and geometrical properties of sea surface. In recent literature, the study of the electromagnetic scattering from contaminated sea surface (sea surface covered by oil spill) was limited in monostatic case. In this paper, we will study this effect in bistatic configuration, which is interested in presence of pollution in sea surface. Indeed, we will start the numerical analysis of the bistatic scattering coefficients of a clean sea surface. Then, we will study the electromagnetic signature from sea surface covered by oil spills in bistatic case using the numerical Forward-Backward Method (FBM). The obtained numerical simulation of bistatic scattering coefficients of clean and contaminated sea surface are studied as a function of various pa- rameters (frequency, incident angle, sea state, type of pollutant...). And the obtained results are also compared with those published in the literature, including those using asymptotic methods.
