Abstract
Taking the attenuation character of the Kelvin wake and the limitation of the traditional two-scale method into account, the practical electromagnetic (EM) scattering model of the Kelvin wake is obtained by using a facet-based model; and for a turbulent ship wake, it is produced by dealing with the wave energy loss rate due to turbulence with the width of turbulent wake closely following a moving ship. The volume scattering theory of foam or bubbles, by using the vector radiation transfer equation, is introduced to modify the traditional two-scale method, a special method for the EM scattering of a turbulent wake, which brings the scattering of ship wakes into better agreement with the real situation.
