A system is disclosed for determining the location from which a sound blast having an identifiable audio signature originates. The system is particrly suited for determining the location of the muzzle blast from which a projectile, such as a bomb, is being launched by an enemy. The system comprises a plurality of elevated or airborne sensors whose position is accurately determined and which supply information to a land base station that performs the trigometric operations to ascertain the location of the enemy weapon.

[ What I claim is:] [1.] A system for determining the location from which the sound of a muzzle blast has been transmitted, said system comprising:(a) an array of elevated sensor platforms having means for detecting signals with characteristic acoustic signatures of known enemy weapons;(b) a means for determining the instant of occurrence of said sound detection;(c) means for determining precise location coordinates of said sensor platforms at the instant of receipt of said sound detection;(d) means for measuring local atmospheric parameters at time of occurrence of said sound detection, and;(e) means for radio transmission of information collected from on board sensor platforms directly to a base station containing a central command processor that processes said data and performs necessary trigonometric operations to solve for the location coordinates of the source of said signal of interest.
