Abstract:

This report documents the results of a study whose objective was to formulate a unified state-of-the-art propagation-loss model capable of handling steep as well as shallow-angle paths in a range-dependent environment. The approach which has been developed would combine the parabolic-equation PE results for non bottom-interacting paths with ray results from FACT or the Multiple-Profile Program--MPP for bottom-reflected paths. This marriage would capitalize on the accuracy of PE for the RR and RSR paths where diffraction effects limit the ray models, while using the ray formulation for the higher-angle paths where diffraction is not dominant and the ray approach is more appropriate.
