Abstract
Each gun of an antiaircraft battery has a unit comprising a laser and a coaxial radiation detector, the axis of the unit being near and parallel to that of the gun barrel. An instrument center, spaced from the guns and controlling their aim, comprises a central sight for target tracking and means for calculating an aiming-off point at which the guns should be aimed when firing real projectiles. For laser practice, projectile flight time is set equal to zero by a switch at the center, so that with correct firing preparations each gun points to a tracked target for detection of laser emissions reflected from it. The laser emits a pulse train for each shot. Hits are scored only on detected trains having a predetermined minimum number of pulses, and scoring is weighted according to error probabilities that would affect real hit results.
