Abstract:

An unresolved radio propagation modeling problem is the effect of a wind-roughened sea surface on propagation at microwave frequencies in the evaporation duct. The biggest deficiency is the lack of suitable experimental data to validate various existing models. In 1994, the Naval Surface Warfare Center Dahlgren Division NSWCDD performed a radio propagation and meteorological measurement program at Wallops Island, Virginia, based on their Microwave Propagation Measurement System MPMS. MPMS consists of 10 transmitters and 4 receivers using 16 discrete frequencies from 2 to 18 GHz. In the 1994 experiment, a 29.4-km over-water coastal propagation path that was over the horizon for the lowest sited transmitters and receivers was used. In this report, these data are analyzed specifically to investigate the effects of a rough sea surface on propagation in the evaporation duct.
