What is Turbulence-noise in Infrared Lidar Sensing about?

An analytical description of the laser location (lidar) systems for investigation of twodimensional distributions of the scattering properties of aerosol fields (natural or anthropogenic) in the infrared range has been made on the basis of the heuristic concept for the influence of the atmospheric turbulence (AT) on the transverse spatial structure of optical radiations. It has been shown that the influence of AT on the information carried by the lidar images is negative. It acts along the path "laser-sounded aerosol layer" only, i.e. when there is utter initial transverse coherency of the optical radiation. Explicit results for the stratifications of the coherency radii, the dispersion and contrast of the transverse spatial fluctuations of the intensity, the averaging action of the apertures of matrix photodetector elements on the corresponding radiant fluxes' turbulent fluctuations and the "signal-toturbulence-noise" ratio have been derived.
