Abstract
An apparatus and method of sniper localization includes an internal clock; an acoustic sensor positioned in a known location and detecting pressure waves; a first processor determining the trajectory of the supersonic projectile, where the first processor includes a shock wave threshold detector receiving time series information and recording arrival times of shock wave components of the pressure waves; a blast threshold detector receiving the time series information and recording arrival times and amplitude information of blast wave components of the pressure waves; a discrimination processor discriminating between a blast wave, a shock wave, or neither, and storing arrival times of each of the potential blast wave components classified as the blast wave; and a localization estimation processor calculating an estimated trajectory of the projectile based on the blast wave and the shock wave arrival times and calculating an estimated firing position of the projectile.
