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 IK distribution in terms of the Rytov variance for plane waves σ12=1.23Cn2k7/6L11/6 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.
