Abstract
By using results from perturbation techniques for weak turbulence and the asymptotic theory for strong turbulence, we develop expressions for the parameters α and ρ of the I–K distribution in terms of the Rytov variance for plane waves and the inner scale of turbulence parameter l0. Comparisons of the resulting scintillation index to experimental data and numerical results from the solution of the fourth-moment equation for 3-D propagation show good agreement.
