Abstract

This work introduces an integral equation formulation to model the radiowave propagation over inhomogeneous smoothly irregular terrain. The ground energy loss is estimated via the Leontovich boundary condition and the fast far-field algorithm accelerating technique is applied in order to improve the computational performance when solving the integral equation. The proposed formulation was implemented in a prediction software named SPRad, which was numerically tested with two measurement campaigns performed in Denmark and Brazil. © 2011 Wiley Periodicals, Inc.
