Relations of the parameters of the I-K distribution for irradiance fluctuations to physical parameters of the turbulence.
By using results from perturbation techniques for weak turbulence and the asymptotic theory for strong turbulence, we develop expressions for the parameters alphaand rho of the I-K distribution in terms of the Rytov variance for plane waves sigma(2)(1)= 1.23C(2)(n) k(7/6) L(11/6) and the inner scale of turbulence parameter l(0). Comparisons of the resulting scintillation index to experimental data and numerical results from the solution of the fourthmoment equation for 3-D propagation show good agreement.
