Abstract :
The theory of operation for a terrain-sensitive propagation path loss model based upon the geometrical theory of diffraction, modified for finite conductivity and local surface roughness, is offered. An evaluation of this new model´s performance with respect to the contemporary Longley-Rice point-to-point model is provided by comparisons of modeled and measured data.
