Numerical estimates of statistical characteristics of optical transfer function of stochastic scattering media

The paper presents two algorithms of the Monte Carlo method for estimating the optical transfer function (OTF) of the atmosphere-underlying surface system Some results of numerical calculations of the mean value of the frequency-contrast characteristics of the scattering coefficients of a random field are presented. The calculations are based on horizontally-inhomogeneous models of the stochastic atmosphere, built on the Palms fluxes. The values, on the average, increase when transferring from the determined model to a one-dimensional stochastic model and then to a three-dimensional stochastic model. The obtained values of the frequency-contrast characteristics (FCC) were used for the correction of the simulated "space snapshots" of test objects.
