Abstract. The solution of a parabolic equation for prediction of the field strength above the earth, allowing for the vertical atmosphere stratification and the geometry of terrain, is considered. The numerical algorithm based on split-step Fourier transform is shown. Solutions for well-known diffraction problems such as spherical earth and a wedge are obtained. The results for real terrain profiles are produced.

Keywords: radio wave propagation, parabolic equation.
