Abstract

Spatial coherence of the reflected wave of a vortex Laguerre-Gaussian laser beam propagating along a location path in a turbulent atmosphere was studied using the methods of numerical simulation. The case of flat mirror target was considered. The split-step simulation method of laser beam propagation was used to obtain mutual coherence function, backscattering enhancement factor and coherence radius of backward wave. The calculations were performed for various values of topological charge of vortex beam and turbulent conditions in atmosphere along the location path. The results are compared with the known results for a Gaussian beam, plane and spherical waves.
