Modern gun-battles are rarely waged on open ground where enemies face each other, and the origins of unfriendly and friendly fire are easy to locate. Instead, many combats are now staged in obstacle-dense situations like cities and forests, where the location of a shooter may be difficult to pinpoint aurally due to reverberations. More importantly, our security forces may not even be present within audible range of all gunshots at all times, due to the highly mobile nature of modern combat. However, in these situations, the personnel would still desire real-time knowledge of the origin of gunshots to prepare prompt and effective counter-measures. The technology under development at NCETIS proposes to address these issues. Specifically, the distinct acoustic signature of gunshots – extremely sharp rise, followed by a slightly slower fall – will be captured simultaneously on multiple microphones. The time delay in the arrival of the acoustic event at multiple microphones will then be processed on a microprocessor in real-time to estimate and report the source of gunfire. The specific application will be for the security of installations like forest camps.
