Accounting of spatial correlation of troposphere refraction index for calculation of coherent component of stochastic electromagnetic field

The aim of the paper is improving the accuracy of calculation of the coherent component of the stochastic electromagnetic field by the numerical solution of the wave parabolic equation. Using the method of geometrical optics, we remove the limitation on the delta-correlated inhomogeneities (Markov approximation). There are tested three models of medium inhomogeneities: Booker-Gordon, Gaussian and Kolmogorov-Obukhov. Estimates of a mean field obtained for each of models were compared with the results obtained in the Markov approximation.
