ABSTRACT: 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.
