This paper presents a new hybrid geometrical optics (GO) and radiance based rough surface scattering model for use in ray tracing propagation models. The reflectance model includes the effects of both specular and diffuse reflection. The specular component is modelled using GO Fresnel reflections, while the diffuse components are modelled using radiance reflectance. The hybrid scattering model is then developed and implemented within an existing three-dimensional microcellular ray tracing model. Comparisons of predicted path loss and rms delay spread are made at 1.92 GHz using site specific measurements in an urban environment. The results demonstrate that scattering can be an important mechanism at this frequency. Significant improvements in prediction accuracy are demonstrated with the new hybrid scattering model.
