Four feet wide and four feet tall, the AN/TPQ-49 Counterfire Radar can watch over a 121-square-mile area. In its original use, it scans for rockets, artillery, or mortar fire, and then feeds those coordinates to troops so the marines can use their own artillery to fire back. Because the counterfire radar is used to tracking small projectiles, the Marine Corps Warfighting Lab hopes it can be adapted to tracking drones. According to the Marine Corps Times, L.K. Philips, head of the lab's Aviation Combat Element, said "he believes it could also track UAVs and even show their launch location, enabling a strike against the drone or its operators." A federal solicitation for spare parts for these radars notes the "computer-controlled signal processing of the radar signal data to perform target detection, verification, tracking, and classification of enemy and friendly mortars."
