Abstract
Passive sensing method is based on cross-correlation analysis of the spatiotemporal structure of turbulent distortions of incoherent video images of surrounding objects. In the process of implementation of the method temporary fluctuations of the local tilts of the wave front is recorded. The tilts fluctuations are estimated by the displacements of centroids of the selected areas of images. Then the estimates of their spatial displacement under the influence of wind transportation on the basis of selected spatial spacing are made. It is possible to use schemes of measurements on the basis of the spacing of the sources (selected pixels blocks of image) and on the basis of the spacing of the receiving lenses. The results of the simultaneous estimation of integral crosswind for the two schemes of the measurements and their combinations are presented in this report on the basis of experimental material.
