| Descripció: | The beam-wander contribution to the scintillation in a ground-to-satellite free-space optical link is one of
major importance. An analytical model, based on the duality between beam wander and angle-of-arrival
fluctuations, is proposed for the temporal statistics. The expression of the probability density function of
the log-amplitude fluctuations is first obtained. Then, the expressions of the spatial and temporal
autocovariances are also obtained. We present plots of the beam-wander contribution to the logamplitude
variance, as a function of the transmitter aperture size and the turbulence accumulated in the
propagation path. We also present the angular fluctuation and log-amplitude scintillation spectrum plots
for some selected cases. © 2005 Optical Society of America |
