US Patent 7755495 Systems and methods of identifying/locating weapon fire including aerial deployment

Systems and methods are disclosed for locating the source of an acoustic event. In one exemplary implementation, there is provided a method of locating the source of an acoustic event by receiving/processing information from at least three sensors aerially deployed across an area to be monitored, wherein each of the at sensors has a microphone for detecting the acoustic event and a known location, the at least three aerial deployed sensors are networked, and time of arrival processing of the acoustic event is performed. In further exemplary implementations, an approximate location of the source of the acoustic event may be determined as a function of arrival time and sensor location data.
