Abstract

Fluctuations in Stokes parameters of stochastic electromagnetic beams on propagation in turbulent atmosphere are studied. The expressions are derived for the scintillation indexes (contrasts) of the Stokes parameters and their versions normalized by the instantaneous intensity in the case when the beam is generated by the electromagnetic Gaussian Schell-model source with uniform polarization. We illustrate our analytical results by numerical examples.
