| Abstract(in English) | This paper deals with a TM plane wave scattering and diffraction from a randomly rough half-plane by a combination of the stochastic functional approach and the Wiener-Hopf technique. The inhomogeneous random scattered wavefield is transformed into a homogeneous random field with a complex wavenumber parameter by the D^a-Fourier transformation. Next, such a homogeneous random field is represented in terms of Wiener-Hermite expansion with unknown Wiener kernels. The hierarchical equations for the Wiener kernels are derived from the boundary condition. Evaluating approximately the scattering process due to surface roughness in the hierarchical equations, a common Wiener-Hopf equation is obtained. Solving the common Wiener-Hopf equation by means of the Wiener-Hopf technique, the Wiener kernels are determined. The random scattered wavefield in the real space is obtained by the D^a-inverse Fourier transformation. |
