Abstract : A rigorous formulation of rough earth parabolic equation (PE) is given. The formulation is based on casting the governing transform equations in terms of incident and reflected plane waves and using the roughsurface reduction factor directly in the spectral domain. Solution is performed by the well known splitstep algorithm. Inclusion of surface roughness into the PE in this manner requires a redefinition of the Fourier transform pair. Several examples are considered showing comparisons with waveguide and other models. (AN)
