Abstract:
It is proposed to use a Gaussian approximation to the coherence function of random electromagnetic field propagating in an inhomo- geneous atmosphere using a numerical method for predicting the coherence function. This approximation is valid in the case of mul- tiple scattering of electromagnetic waves. Then it is sufficient to determine only values of three coherence function parameters. It is the dispersion, range of spatial correlation and preferred direction of wave propagation. Equations for each parameter were de-rived. These equations describe the variation of the parameters in an inhomogeneous medium for one step in range.
