This paper describes an airborne deployment of the Viper sniper detection and counter fire system and several improvements that were incorporated after a review of comments from users of the fielded systems. The Viper sensor was flown aboard a T-34 aircraft and the Naval Research Laboratory NRL Sparrow unmanned aerial vehicle UAV. Infrared IR and visible video sequences were recorded for post processing. Algorithms for motion compensation, frame registration and target detection were then developed to run on the collected image data. No inertial attitude data were recorded and all motion compensation functions were made using image data. These experiments indicate that automatic detection of muzzle flash from an airborne platform is possible, and techniques that were developed for background estimation and false alarm reduction with a stationary sensor can apply with modifications to a moving sensor.
