ABSTRACT:
This invention is an automatic gunnery system, responsive to airborne acoustic shock waves produced by a projectile passing through a target area. The invention relates specifically to the "hit" location of the said projectile for the condition when the flight path of the projectile is not perpendicular to the target area. Two pairs of concentric curved elongated acoustic energy conductors (curved sensor rods) 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 signals from the transducers are connected to electronic circuitry and a calculating computer which calculates the intersection of two circles and determines the location of each "hit" on or near the target with each "hit" registered on a graphical display means.
