Abstract: A wearable shooter localization system including a microphone array, processor, and output device for determining information about a gunshot. The microphone array may be worn by on the upper arm of the user. A second array, which may operate cooperatively or independently from the first array, may be worn on the other arm. The microphone array is sensitive to the acoustic effects of gunfire and provides a set of electrical signals to the processing unit, which identifies the origin of the fire. The system may include orientation and/or motion detection sensors, which the processor may use to either initially compute a direction to the origin of a projectile in a frame of reference meaningful to a wearer of the system or to subsequently update that direction as the wearer moves.

Abstract: A system for processing one or more detection signals from an acoustic signal detection system to image and track one or more contacts within a medium including a computer configured to receive the detection signal and a computer readable medium operatively coupled to the computer, that is capable of applying an image processing method to one or more images derived from the received one or more detection signals to estimate the kinematic characteristics of the one or more contacts.
