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 ...

An Evaporation Duct Height Estimation Algorithm Based on Deep Neural Networks
Journal of Physics: Conference Series, 2022 Abstract In order to solve the problem of the evaporation duct height (EDH) estimation, focusing on the propagation loss (PL) features with different EDHs, this paper proposes an evaporation duct height estimation method based on Deep Neural Networks (DNN). The theoretical basis is Universal Approximation Theorem.
