Abstract

For solving a large number of problems on optical radiation propagation in the atmosphere the atmospheric turbulent characteristics should be determined. There are the inner l₀ and outer L₀ scales of turbulence, structural characteristics of fluctuations of the refractive index $C_n^2$. The value of $C_n^2$ determines the turbulence intensity. All these characteristics are the parameters in the spatial spectral density φ_n (x). The function is given as [1,2] where x_m=5,92/l₀, x₀=2π/L₀. In the inertial subrange (x₀≤ x ≤ x_m) the model (1) coincides with the Kolmogorov spectrum of turbulence.
