The influence of turbulence on formation of image of a laser beam by the receiving optical system was studied experimentally for the case of reflection from a mirror. The beam was focused on a reflector through both correlated (monostatic) and uncorrelated (bistatic) paths under conditions of strong intensity fluctuations. Intensity distributions in the plane of the reflector image were recorded and analyzed. It was shown that under certain conditions on the correlated path the intensity distribution has two scales, wide base (turbulent radius), and a narrow peak (coherent radius). The dependence of the radius of the beam image on the conditions of propagation and the diameter of the receiving objective was determined.
