Abstract

The US Army is currently investigating the use of acoustics to locate and discriminate tank rounds fired during live-fire training exercises for armored vehicle gunners. Being able to determine round type and location at the intended target greatly enhances training realism. By determining a round's velocity, miss distance from a sensor and acoustic shock wave duration, the round can be classified into one of five size categories. The round's location at the target is calculated as a by-product during the determination of miss distance. A prototype acoustic discrimination system has been developed that consists of a microprocessor with multichannel A/D hardware and a few acoustic sensors. For each round fired, the prototype system calculates a projectile shape value (PSV) from the round's velocity, miss distance, and shock wave duration. The PSV is then compared to a look-up table to classify the round according to size. Initial tests of the prototype acoustic round discrimination system have been successful.
