"Ferreting out sniper threats
Recently deployed in Afghanistan, the FERRET provides the Canadian Forces with better protection against snipers. The FERRET is a passive acoustic system for the detection and localization of small-arms fire at long ranges. The system is composed of a three-dimensional microphone array mounted on the rear of the turret of the Coyote light armoured reconnaissance vehicle. The system processes the sound signals and shows the results on a hand-held terminal by means of a graphical and numerical display. "
