Abstract

Atmospheric turbulence causes intensity fluctuations in the received beam of a ground to space laser communication link. Theoretical analysis of the beam propagation through atmospheric turbulence to a satellite shows that very accurate pointing of the transmitter beam will reduce the fading of the signal. A new technique for tracking through turbulence is described that uses enhanced backscatter resulting from reciprocal scattering paths. Laboratory experiments have been conducted and data compared to computer simulation. A plan has been developed for demonstrating the technique on a Low Earth Orbiting satellite.
