Abstract:

An analytical and experimental program is described to assess the effect of evaporation ducting on radio propagation. Extensive meteorological and radio propagation measurements were conducted and checked against computer calculations. Particular emphasis was given to the influence of antenna height on detection range under a variety of ducting conditions. A computer program has been developed which models radio propagation in the evaporation duct using mode theory.
