Electromagnetic Scattering from Rough Sea Surfaces Contaminated by Oil Spills

As a theoretical basis for remote sensing of marine oil spills, electromagnetic scattering signatures of radar echoes from contaminated sea surfaces are investigated in this paper. Numerical simulations show that at normal incidence the angular distribution of bistatic scattering intensity of contaminated sea surface is more concentrated and higher than that of clean sea surface, and that at moderate incidence angles the backscattering intensity is reduced, which is qualitatively consistent with measurements.
