A heuristic model of aperture-averaged angle-of-arrival variance for a Gaussian wave propagation through anisotropic non-Kolmogorov turbulence

摘要

This paper investigates the aperture-averaged angle-of-arrival variance for a Gaussian wave propagating through the weak anisotropic non-Kolmogorov atmospheric turbulence along a horizontal path. A heuristic model is deduced from the results of plane and spherical waves under the geometrical optics approximation. The mathematical expression include the spectral power law value, the anisotropic factor and other essential optical parameters of a Gaussian wave.
