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-stat istical 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 s imulation results are presented and analyzed within a physical point of vie w, The shadowing correlation model is finally applied to several low-earth- orbit constellations, The impact of geometrical parameters and of the const ellation is investigated.
