A physical-statistical shadowing correlation model and its application to low-Earth-orbit systems

A shadowing correlation model is proposed in the context of a physical-statistical approach in the view of satellite diversity in built-up areas. The model relies on a model based on the uniform theory of diffraction, applied in a canonical built-up scenario. The correlation model is described and simulation results are presented and analyzed within a physical point of view. The shadowing correlation model is finally applied to several low-Earth-orbit constellations. The impact of geometrical parameters and of the constellation is investigated.
