“…However, results from laser wave propagation experiments in the past along horizontal paths near the ground, and more recently over very long paths as well as vertical paths, show that the atmospheric turbulence can deviate from the standard isotropic Kolmogorov spectrum [5,6]. In our previous papers on this subject [7,8], we developed analytical expressions for the log-amplitude correlation of a plane wave that is valid in the low to moderate regimes of integrated path turbulence, for fixed turbulence strength along the path. In this paper, we develop a similar general expression for the log-amplitude correlation of a spherical wave propagating through anisotropic non-Kolmogorov turbulent atmosphere.…”
