Abstract
The report considers the possibility of estimation of the profile along the optical path of the transverse wind velocity component from fluctuations in the image of a diffuse target illuminated by a laser beam. An algorithm for processing video images based on the construction of a spatiotemporal correlation function of fluctuations in the intensity of radiation scattered from a target is proposed. The results of testing the proposed technique by means of numerical simulation and in experiments at the IOA SB RAS test site are presented.
