Systems and methods of identifying/locating weapon fire including aerial deployment
First Claim
1. A method of processing data associated with acoustic weapon fire events, the method comprising:
- performing aerial deployment of at least three aerial sensors across an area to be monitored, wherein each of the at least three sensors comprises a microphone for detecting a weapon fire event, and wherein the location of each of the at least three sensors is known;
networking the at least three aerial sensors via a network;
processing signals communicated over the network from one or more sensors that detect the weapon fire event, wherein the signals include time of arrival data as to when a muzzle blast from with the weapon fire event was detected at the one or more sensors, with each time of arrival being obtained from a synchronized or absolute time source associated with a sensor that detected the weapon fire event; and
determining an approximate location of a source of the weapon fire event as a function of arrival time and sensor location data;
wherein the approximate location of the source of the weapon fire event is determined as a function of one or more of temperature, relative humidity, and/or air pressure.

Abstract
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.
