Reconstruction of the wind velocity profile by the intensity fluctuations of a scattered wave in a receiving telescope

摘要

The problem of the wind velocity profile reconstruction from random intensity fluctuations of a laser beam diffusely scattered by a screen and received by a telescope is considered. Expressions for a spatiotemporal correlation function and spectrum of weak intensity fluctuations of the reflected beam are presented. An algorithm is proposed for the reconstruction of the profile and direction of the wind velocity from the intensity fluctuation spectra of reflected radiation received by the telescope. The efficiency of the algorithm is confirmed by the results of numerical experiments.
