“…In our simulations we have used the numerical FBM method to calculate the electromagnetic scattering coefficients of a clean and a polluted sea surface. It should be noted that the chosen method (FBM) in this work has already been applied in different applications, in particular it has been used to calculate the electromagnetic signature of a breaking wave, and the results obtained in this context were compared with experimental measurements made in the anechoic chamber (at ENSTA Bretagne) with profiles of breaking waves in aluminum [18] [19]. Thus, we will start the numerical simulation of the pollutant effect on the physical and geometrical properties of sea surface.…”

The aim of the work presented in this paper focuses on the study and analysis of variations of the bistatic electromagnetic signature of the sea surface contaminated by pollutants. Therefore, we will start the numerical analyses of the pollutant effect on the geometrical and physical characteristics of sea surface. Then, we will evaluate the electromagnetic (EM) scattering coefficients of the clean and polluted sea surface observed in bistatic configuration by using the numerical Forward-Backward Method (FBM). The obtained numerical results of the electromagnetic scattering coefficients are studied and given as a function of various parameters: sea state, wind velocity, type of pollutant (sea surface polluted by oil emulsion, and sea surface covered by oil layer), incidence and scattering angles, frequencies bands (C, X and Ku) and radar polarization.

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]).
