The 1D band-limited Weierstrass fractal rough surface is proposed for describing the natural rough sea surface. The composite electromagnetic scattering between the fractal sea surface and the above vortical rectangular cross section conductor column is investigated using a hybrid method associated the method of moment (MOM) with the Kirchhoff approximation (KA). By comparing the results from the different incidence angles with the classical result calculated by the MOM method, it is obtained that the hybrid algorithm has a higher accuracy and computational efficiency. Finally, the dependencies between the composite scattering coefficient and the parameters including the rough sea surface, target parameters and incident wave parameters are discussed, and the more complete electromagnetic scattering characteristics are obtained.
