Annotation

Factors affecting amplitude and phase fluctuations in detection-and-rangingtype optical systems under alternating atmospheric turbulence conditions are considered. Experimental data characterizing, as applied to a narrow collimated laser beam, the effects of random wandering, turbulence broadening, and variation of the correlation radius of the intensity fluctuations are obtained and analyzed. The sporadic radiation stochastization observed is explained by the sharp reduction of the internal turbulence scale in comparison with the average beam size.
