Atmospheric turbulence profile modeling for satellite-ground laser communication

Profiles of the index of refraction structure parameter (Cn2), as well as inner and outer scales of turbulence, are of high importance to estimate and predict the channel behavior characterizing satellite to ground optical links. The Cn2 HufnagelValley model is up to date the most commonly used one due to its simplicity and relative accuracy. However, it can be quite inadequate especially for ground station sites that are situated at important heights above mean sea level. Thus, it seems legitimate to search for a better model that suits the characteristic demands of the satellite to ground link scenario. The work undertaken during this thesis was further motivated by the fact that for the design of a particular communication link, a good understanding of the propagation channel is necessary. Therefore the study presented in this manuscript aimed to identify the status-quo of atmospheric turbulence modeling (structure parameter constant, inner and outer scale profiles) options, by conducting a bibliographic work as extensive as possible and, by assessing with respect to realism, applicability, advantages and drawbacks (especially by the calculation of particular channel parameters) the models referenced.
