Abstract
This quarter the reflection and scattering models were further developed, and a review of the literature preliminary to the development of a convergence zone propagation model was completed. In Section II, expansion of the heuristic scattering model to include composite (both large and small scale roughness) surface statistics is given which sould improve backscattering predictive capabilities. This model does not include slope correction terms but has the advantage of simplicity. The more rigorous theoretical model which includes slope corrections terms is also expanded to allow for composite surface roughness. A survey of the literature covering convergence zone propagation is summarized in Section III. An approach is outlined for the development of a convergence zone model using a Green's function expansion. This technique results in an ordered integral expansion where each integral can be associated with a particular multipath. (Author)
