The electromagnetic scattering from oil-covered sea surface is investigated by two scale model with the help of Lombardini's oil-covered sea spectrum and the semi-empirical reflection model that takes the oil film into consideration. Firstly, a comparison of the clean and oil-covered sea spectra is made to show the influence of the oil film on the sea surface. Then, the backscattering coefficient from the clean sea computed by the two scale model is compared with the measured data in the reference to validate the accuracy of the two scale model used in this paper. Finally, backscattering features from the oil-covered sea surface are discussed in detail and compared with those from the clean sea. In addition, the influence of the thickness of oil film and fractional filling factor on the backscattering coefficient of oil-covered sea are also studied. The simulated results show that the oil film floating on the sea has remarkable influence on the backscattering coefficient of the sea, compared with those of the backscattering coefficient from the clean sea.
