Terrain Modelling Using the Split-Step Parabolic Equation Method

Abstract

There are currently several software programs that model radiowave propagation over irregular terrain. These models use a combination of spherical earth diffraction, multiple knife-edge diffraction, wedge-diffraction, and geometrical optics to arrive at a solution for the field for a given transmitter/receiver geometry and a specified terrain path. More recently, parabolic equation (PE) methods have been applied to model propagation over terrain, such as that developed by Levy....
