Abstract : A unique piezoelectric device has been developed to meet the Army's need for a more effective and economical sensor for the hit detection system used on rifle and tank firing ranges. The new sensor was designed to replace a relatively expensive unit that works well on a sheet metal target but is difficult to install and is not adaptable to cheaper target materials. Field tests showed that the new sensor is not only a more effective impact detector than the original sensor, but is capable of discriminating against false indications that may be caused by muzzle blast, debris thrown against the target by near misses or short rounds, and vibrations from other causes such as wind. Costing less than half as much as the original sensor, the new unit promises the additional economies of low maintenance and replacement costs on the basis of its durable performance in rifle firing tests.
