Modelling Specular and Non-Specular Propagation Components for Statistical Analysis of Clutter Loss in G2S Links

A comprehensive methodology is proposed for modelling specular and non-specular propagation components within the framework of statistical evaluation of clutter loss in Ground-to-Satellite (G2S) links. The approach, which is physically consistent, aims at developing an effective reflection coefficient that inherently accounts for both propagation phenomena, evaluated in the direction of the satellite. The methodology is shown through a reference study case, detailing the underlying assumptions and distinguishing between different wave polarizations. The proposed approach can be directly incorporated into a well-assessed stochastic simulator for the prediction of the clutter loss in G2S links, thereby improving its accuracy, particularly at frequencies that may be exploited by incumbent terrestrial networks.
