An Experimental Study of the Effects of the Evaporation Duct on Microwave Propagation
OCEANS 2019 MTS/IEEE SEATTLE, 2019 This paper presents the results of a study on the effects of the evaporation duct on microwave propagation in the Irish Sea. The evaporation duct is a phenomenon that occurs almost permanently over the earth's oceans and can be exploited to enable over the horizon communications in the marine environment.

Estimating Range-Dependent Evaporation Duct Height
Journal of Atmospheric and Oceanic Technology, 2017 AbstractThe refractivity from clutter (RFC) technique has been proved to be an effective way to estimate atmospheric duct structure. An important issue for RFC is how to make the estimate more robust, especially in range-dependent ducting conditions. Traditionally, statistical inversion methods need a large number of forward propagation model runs to ...
