Installation for the measurement of the altitude of a surface wind, particularly for improving the hitting accuracy of unguided projectiles

An installation for the measurement of the wind direction and the wind velocity of a ground wind dependent upon the altitude above the ground. More particularly, the installation is employed for improving the hitting accuracy of unguided projectiles or rockets. The installation incorporates a vertically-orientable firing barrel or launching tube for the launch or firing of a measuring projectile, a speed measuring installation for the measurement of the launching speed of the measuring projectile from the launching tube, an optical camera device for the photographing and digitalizing of successive pictures of the measuring projectile which is fired from the launching tube taken in timed sequence. The camera device is positioned adjacent the launching tube oriented in parallel therewith, an electronic data processing unit being connected with the camera device for determining the current position of the measuring projectile in accordance with the successive digitalized pictures, and a display arrangement which is operatively coupled with the electronic data processing unit for the display of the wind direction computed through the electronic data processing unit, and the velocity of the wind dependent upon the altitude of flight of the measuring projectile.
