Paper Abstract

In the report the results of investigation of spatial coherence of electromagnetic wave dependence on statistical characteristics of air density inhomogeneities within the altitude interval 20-70 km are presented. The electromagnetic field characteristics are evaluated in frame of phase shifting screen approximation at the plane placed 2×l03 - 4×103 km behind atmospheric layer. Considering the impact of outer scale of anisotropic atmospheric inhomogeneities on spatial coherence of registered wave the statistical homogeneity on sphere of the refraction index fluctuations is taken into account. In case of infinitely large outer scales the spatial coherence of the wave affected by the random fields with power-law structure functions is proved to be remaining partially whence the power index exceeds 4 in contraposition to the case of statistically homogeneity in space.
