Abstract

In this paper an algorithm for sniper localization using disparate single microphone sensors that uses only the time difference of arrival (TDOA) between muzzle blast and shock wave is presented. Just as in any algorithm that looks for optimal solution this algorithm also faces the local minima (possible sniper locations) problem. In order to find the global or near global solution one has to perform search over a large area. In order to reduce the computational burden, the search space needs to be small. In this paper, an upper and lower bound on the range for the search space are estimated using the sensor configuration. Based on this, the area around the bullets path is searched with the bounds on range to determine the exact or near global solution for the sniper location. The results of sniper localization algorithm applied to real data collected in a field test will be presented.
