Abstract
We propose a relatively simple and convenient approximate expression for the spherical structure func-tion in atmospheric turbulence having the Von-Karman spectrum. The approximation, which is accurate to within 6%, is valid for any separation between the observation points. In the asymptotic intervals 2rp«to, to«27p((Lo, 27rp))Lo the approximate expression coincides with the known analytical solutions. An approximate expression is presented also for the coherence length ρo) for the case of homogeneous tur-bulence conditions along the propagation path.
