Abstract:
Comparison of the data modeling of the laser beams on the basis of a parabolic equation for the complex field amplitudes waves with the available theoretical and experimental results shows that for a quantitative evaluation in many cases it is required to simulate the random phase screens in the lower-frequency part of the spectrum than it allows you to step sample computational grid . Experimentally shown that anisotropic boundary layer near the surface, turbulence is locally weakly anisotropic and similarity theory by Monin -Obukhov you - holds locally. On the basis of calculations and analysis of the cited studies may be noted that the use of the correction phase correction leads to improved telecommunications system, in comparison with the method of wavefront correction Sarka - Hartmann throughout the range of variations in levels of atmospheric turbulence C-1: from 1E- 16 to 1E -12.
