摘要：
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.
