Abstract

Possibilities of retrieval of the drift velocity of atmospheric turbulence inhomogeneities from a video sequence of incoherent images of an object are studied numerically in the work. A method for filtration of turbulent distortions of an image by their characteristic sizes is suggested with the aim to determine the wind speed at different segments of an observation path. The method testing for the cases of two layers of turbulent inhomogeneities that drift in different (mutually normal) directions has shown high accuracy of retrieval of their drift velocities.
