Title

The Effect Of Partially Coherent Quasi-Monochromatic Gaussian-Beam On The Probability Of Fade

Abstract

The effect of a (spatially) partially coherent quasi-monochromatic lowest order Gaussian-beam on the direct detection system is studied in weak and strong atmospheric turbulence. The analytic expression for the scintillation index has been developed and analyzed as a function of the spatial correlation distance l c and the correlation time τ S, associated with the source, as well as the strength of turbulence and the integration time τ d of the detector. The probability of fade is also discussed as a function of relative detector speed τ d / τ S including limiting cases of slow (τ d≫τ ss) and fast (τ d≪τ s) detector.
