Abstract :
A problem of radio wave propagation modeling over the Earth surface in approximation of parabolic equation is investigated. The features of three-dimensional model and the dependences of prediction results on the size of the considered domain, the numerical scheme and the parameters of the transmitter are analyzed. There was made a comparison with known theoretical results for a case of a triangular hill and with prediction results of a two-dimensional model.
