Statistical Modelling and Analysis of Conditioned Clutter Loss in Earth-to-Space links for U6G Interference Evaluation

This study focuses on the statistical modelling and analysis of conditioned clutter loss in Earth-to-Space links, supporting coexistence between terrestrial and nonterrestrial systems in the U6G band. A clutter loss stochastic model, based on a Monte-Carlo simulation, enables to generate simultaneous rays emitted from terrestrial base stations with opposite elevation angles, allowing for the independent evaluation of the clutter loss experienced by each of these rays. Conditional clutter loss distributions at 6 GHz, derived for a reference urban environment such as London, reveal the dependence on the satellite elevation angle and highlight the general predominant contribution of ground-reflected components to the overall clutter loss observed at the satellite.
