8,325,563: Systems and methods of locating weapon fire incidents using measurements/data from acoustic

  • Type: US
  • Application Number: 12/154,968
  • Publication Date: Jul 19 2012
  • Filing Date: May 27 2008
  • Abstract:

    Systems and methods are disclosed for locating a weapon fire incident such as an acoustic transient from a gunshot, explosion, weapons launch, etc. In one exemplary implementation, there is provided a method of locating the incident from a combination of propagation phenomena including a discharge time of the weapon fire incident. Moreover, the method may include obtaining a first propagation parameter of the incident from one or more first sensors, obtaining the discharge time from another sensor, and processing the data to determine a location using a common time basis among sensor measurements. According to further exemplary implementations, the discharge time may include a transient event that has a different propagation velocity than that of sound in the atmosphere.
