Paper Abstract

The results of the theoretical investigation of a random image displacement of a light beam after passing through a turbulent atmospheric layer with precipitation are presented in the paper. Statistical characteristics of a light beam propagating in a turbulent atmosphere containing a large number of discrete "optical soft" large-scale bodies have been examined in the approximation of a model of continuous randomly-inhomogeneous medium. Variance of image has been calculated based on an asymptotic solution of equation for a fourth-order mutual coherent function of a field. Contribution of the atmospheric precipitation (rain) to fluctuations of the center of gravity displacement of infrared radiation beam image is shown to be important practically for different sizes of receiving apertures. Cases of "weak" intensity fluctuations have been considered.
