An experimental study of fading in propagation at 3-cm wavelength over a sea path

The paper describes an experimental study of fading in propagation over a sea path within the radio horizon at a wavelength of 3 cm carried out between July 1950 and January 1951. Horizontal polarization was used. The object of the investigation was to record the general fading characteristics (i.e. depth, duration and frequency of occurrence) for summer, autumn and winter and to present the results in such a form that the effects of fading on the operational ranges of radar equipments could be readily appreciated. An initial assessment of the transmitter power required for reliable operation of a beacon under given conditions has also been made.
