Abstract
A system and method for identifying the location of gunfire from a moving object in which at least two spaced apart microphones are positioned on the moving object. The output from the microphones is decomposed into intrinsic mode functions by using empirical mode decomposition. A transient pulse is then identified in the intrinsic mode function representative of the gunfire. The location of the origin of the gunfire is then determined from the transient pulses through multilateration using time difference of arrival of the transient pulses by the microphones.
