Paper Abstract

In planned intersatellite optical communication systems, the optical payload on board the geostationary satellite will be periodically pointed towards an Optical Ground Station. When the satellite-ground link is established, the turbulence-induced disturbances must be taken into account. The subject of this paper is to assess the statistics for the power fadings that result from the instantaneous point-spread function distortion. Results predicted by an approximate technique which considers the instantaneous point-spread function as a gaussian intensity distribution displaced from the focus due to the angle-of-arrival tilt are compared against results obtained from wavefront simulations produced by fractal generation techniques. The reduction in the cumulative probability of losses that can be obtained by spatial averaging using a multiaperture receiver is also assessed.
