Abstract

In this paper, electromagnetic scattering from rough sea surfaces with a ship-induced induced Kelvin wake is investigated by utilizing the polarimetirc scattering model of second-order small-slope approximation (SSA-II) with tapered wave incidence for reducing the edge effect caused by the limited surface size. The emphasis of this study is on the examination of the effect of ship-induce wake on backscattering scattering signatures of rough sea surfaces, due to the presence of ship-induced wake can significantly change sea surface's geometric structures especially for low wind conditions. Numerical simulations also show that the scattering signatures in the presence of a ship-induced wake significantly differ from those without wake, which is of great importance for the detection of ships in marine environment.
