Abstract

A laser generator (1,2,3) is arranged to generate successive pairs of pulses. Two light receivers (10,11) in the vicinity of the laser generator receive echos of the pulses as reflected from a target and a processing circuit (15) calculates the component of wind speed blowing across the laser axis between the laser generator and the target. The device can be combined with laser ranging means and used for artillery control.
