Abstract
The attenuation factor of a centimeter wavelength signal versus the path length is studied considering the evaporation duct presence in different regions of the World’s ocean. An empirical dependence has been derived between the evaporation duct height and the direct signal attenuation at different path lengths. An experimentally sampled technique is suggested to determine the attenuation factor, which is used for ship borne radar range diagnosis and prediction.
