“…Among the exact methods, in our study the numerical FBM method is used to calculate the bistatic scattering coefficients from a clean and a polluted sea surface. It should be noted that the chosen method (FBM) in this paper has already been applied, in particular to calculate the electromagnetic signature of a breaking wave, and the results obtained in this context were compared with measurements made in the anechoic chamber with profiles of breaking waves in aluminum [19,20].…”

The aim of this work is to study the impacts of the oil spills on the electromagnetic scattering of the ocean surfaces in bistatic and monostatic configurations. Therefore, in this paper, we will study the influence of the pollutants (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 is studied as a function of various parameters (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.

In this paper, we will present an experimental validation of the results given in [1] about the hydrodynamic phenomena (nonlinear) produced by the breaking coastal waves on the copolar scattering coefficients in the bistatic configuration (especially in forward propagation case). Actually, we have carried out different X-band experimental measurements of aluminum wave profile in an anechoic (echoless) chamber (Ensta Bretagne), which was calibrated (EMSL Simple Polarimetric Calibration [2]).
