Abstract
In this report, the results of simulation are presented of multichannel radiation propagation in the atmosphere. Correction of turbulent distortions on the basis of the beam phase control is considered. The results demonstrate the dependence of the correction effectiveness on the number of channels and on precision of reference beam phase reconstruction. Additional increase of the effectiveness is possible with adjustment of amplification in the channels of the optical system, i.e., with the use of amplitude-phase control of radiation.
