Paper Abstract

A model of irradiance fluctuations for a propagating optic wave through a random medium is developed here under the assumption that small-scale irradiance fluctuations are modulated by large-scale irradiance fluctuations of the wave. The upper bound for small turbulent cells is defined by the smallest cell size the Fresnel Zone or transverse spatial coherence radius of the optical wave. The largest cell size between scintillation index, we also develop expressions for the irradiance covariance function and temporal spectrum of irradiance. Quantitative values predicted by these models agree well with experimental and simulation data previously published. An application of the method is also presented for uplink/downlink optical communication channels to/from a satellite.
