Abstract

In this paper we discuss some recent results concerning beam wander-induced scintillation of a Gaussian-beam wave along a horizontal path with constant C²_n and also from ground to space, the latter based on the Hufnagle-Valley C²_n. We consider cases of tracked beams and untracked beams, both of which involve a certain amount of beam wander. Theoretical models of scintillation and corresponding probability density function (pdf) models are compared with simulation data over a broad range of beam diameters. We include both collimated and focused beams. For the uplink from ground to space path, we also examine some fade statistics.
