The effect of a random phase screen on laser beam wander in a turbulent atmosphere is studied theoretically. The method of photon distribution function is used to describe the photon kinetics of both weak and strong turbulence. By bringing together analytical and numerical calculations, we have obtained the variance of beam centroid deflections caused by scattering on turbulent eddies. It is shown that an artificial distortion of the initial coherence of the radiation can be used to decrease the wandering effect. The physical mechanism responsible for this reduction and applicability of our approach are discussed.

“…4, was conducted following the method described in Dios et al (2008), where the field profile for different exposure times is presented. For this simulation it was assumed a propagation distance of Fante (1980) in his work relate the random displacements of the incoming wavefront center or "hot spot" with the long-term W LT and short-term W ST spot sizes, assuming that the "hot spot" coincides with beam centroid, by the expression…”

“…In electromagnetic wave propagation through the earth's atmosphere like satellite communications, it is known that random fluctuations of the dielectric constant of atmosphere affect propagation characteristics of electromagnetic waves (Fante, 1975;1980;Ishimaru, 1997;Rytov et al, 1989;Strohbehn, 1977;Tatarskii, 1961;1971;Tatarskii et al, 1993;Uscinski, 1977;Wheelon, 2003). The random fluctuations, called atmospheric turbulence, cause spot dancing, wave form distortion, scintillations of the received intensity, the decrease in the spatial coherence of wave beams etc.…”
