Abstract

The paper presents the results of a study of the backscattering enhancement of optical beams propagated on monostatic location paths in the turbulent atmosphere. The backscattering enhancement factor (BSE) behavior of vortex LaguerreGaussian beams was investigated in conditions of the weak turbulence fluctuations of light intensity. It is shown that, unlike light beams with a regular wave front, the dependence of BSE factor of the average intensity of the vortex beams on the optical turbulence intensity has a saturation level determined by the value of the topological charge and the radius of the diffuse target.
