System and methods for detecting shooter locations from an aircraft
First Claim
1. An airborne shooter detection system for a helicopter, comprising:
- a plurality of sensors spaced apart on the surface of the body, including at least on the bottom and sides of the helicopter, wherein the plurality of sensors are configured for receiving signals indicative of one or more characteristics of a shockwave of a projectile, and the plurality of sensors are distributed from about the nose of the helicopter to about the tail of the body of the helicopter such that for each of a plurality of different helicopter orientations, at least five of the plurality of sensors can receive the shockwave;
a processor in communication with a plurality of sensors configured for unambiguously determining the location of the source of the projectile; and
an output device in communication with the processor for outputting the determined location.

Abstract
The systems and methods described herein relate to an airborne shooter detection system having a plurality of sensors coupled to the body of an aircraft such as a helicopter. The system includes at least five sensors configured and arranged to disambiguate the location of a shooter. By measuring the arrival times of the shockwaves of projectiles at each of the sensors and determining the differences in the arrival times among sensors, the systems and methods may determine the location of one or more sources of the projectiles. A distance of at least ten meters separates two or more of the sensors. Such a separation is advantageous because it allows the system to disambiguate multiple shooters by resolving the curvature of the shockwave.

14. A method for locating a source of a projectile fired at a helicopter, comprising:
-
receiving, at a plurality of sensors mounted on a helicopter, signals indicative of one or more characteristics of a shockwave of a projectile fired at the helicopter, wherein the plurality of sensors are distributed from about the nose of the helicopter to about the tail of the helicopter such that for each of a plurality of different helicopter orientations, at least five of the plurality of sensors can receive the shockwave; analyzing the signals to unambiguously determine a location of a source of the projectile; and outputting the location of the source. - View Dependent Claims (15, 16, 17, 18, 19, 20)
