| Popis: | The similarity model of anisoscale fluctuations of permittivity in a turbulent atmosphere is suggested. Correlation properties of fluctuations in different spatial directions are shown to be similar and to differ only in the direction-dependent scaling factor. The power-law similarity model of fluctuations is proposed. It is shown that in the geometric optics approximation the correlation properties of the phase of plane (and spherical) wave are similar and differ only in the scaling factor, depending on wave-propagation directions and the base (the coordinate difference at probe points). Correlation characteristics (dispersion, coefficient of anisomery, and a form of correlation coefficient) are calculated for a number of typical parameters of the problem. |
