ABSTRACT:
This invention is an automatic gunnery system, responsive to airborne acoustic shock waves produced by a projectile passing through a target area. Curved elongated acoustic energy conductors are located adjacent to one side of said target area with acoustic transducers attached to the end portions thereof. Said transducers produce an electrical signal when a shock wave from the projectile reaches them through said energy conductors. Electrical signal from the transducers is connected to electronic circuitry which determines the location of each "hit" on or near the target which is registered on display means.
