Abstract
The results of the statistical analysis of experimental data obtained during the polygon tests of a passive optical wind speed meter are presented. During the tests, a possibility of using the device for aiming correcting to compensate the wind shift of bullets was evaluated. During the experiments, the arrays of the coordinates of the impact points and the values of the component of the wind speed averaged over the line of sight were recorded; the one-to-one correspondence of the elements of the arrays was not established. A method for determining the coefficient of linear interrelation for such arrays is proposed. It is shown that taking into account the corrections formed on the basis of wind measurements by a passive optical meter decreases the spread of the impact points to values corresponding to shooting standards for the best snipers in the absence of wind.
