Аннотация
Possibilities for the crosswind profiling along a path of observation of a distant object from the analysis of the video sequence of its images are studied in this work by numerical simulation. The method suggested for wind velocity estimation is based on the analysis of two adjacent incoherent images and exhibits better performance in comparison with counterparts, which is explained by there being no need to accumulate statistics of the parameters analyzed. A new method for the filtration of turbulent distortions of an image by their characteristic sizes is suggested with the aim of estimating the wind velocity in different segments of an observation path. The work shows a possibility of determining the drift velocity of several (no less than three) layers of turbulent atmosphere, located at different positions between the object observed and receiving optical system, under certain turbulent conditions.
