Backscattering enhancement factor dependence of a Laguerre- Gaussian laser beam propagating on the location path in the atmosphere on optical turbulence intensity

摘要

The paper presents the results of a study of the backscattering enhancement factor (BSE) dependence of vortex Laguerre-Gaussian beams propagating on monostatic location paths in the atmosphere on optical turbulence intensity. The numeric simulation split-step method of laser beam propagation was used to obtain BSE factor values of a laser beam propagated on monostatic location path in the turbulent atmosphere and reflected from a diffuse target. It is shown that BSE factor of the averaged intensity of a backscattered vortex laser beam of any topological charge is less than BSE factor values of backscattered Gaussian beam in arbitrary turbulent conditions.
