Troposcatter effects prediction: Ray-tracing modeling for radio links

This ray tracing technique addresses the profiling of the field intensity in radio links in presence of tropospheric multipath. Care is taken in the identification and separation of the different field contributions due to wave folding and the interaction between the rays and the terrain. Unwrapping the ray comb enables interpolation on single folds without ambiguity. The various steps toward the field estimation are detailed with two examples: with an atmosphere with only vertical variation and with variations in both directions.
