Method of estimation of the cross-wind velocity from statistics of energy centroids coordinates of binocular images of topographic objects

摘要

In the report the method of evaluation of the crosswind velocity from the jitter statistics of binocular images of a remote topographic objects and the results of experiments on atmospheric paths are presented. The possibility of evaluation of the cross-wind based on the shift of the maximum of the mutual correlation function of the displacements of the energy centroids of areas of contrast images is demonstrated. The horizontal spacing of the objectives allows to evaluate the integral speed, and the diagonal spacing - the value of the velocity at a specific point of the optical path. Speed estimates derived from passive optical method agree with the results of independent means of measurement.
