The highly mobile Firefinder radars AN/TPQ-36 and larger AN/TPQ-37 can immediately locate enemy fire. System activates when hostile projectiles penetrate the scanned areas, before they even reach the target(s), the Firefinder radar back-plots and transmits enemy artillery and mortar positions, in precise coordinates, to friendly artillery fire centers to allow for counter-battery fire. The radar uses separate tracking channels and traverses in sector increments through 360 degrees. An operations shelter is set up on a cargo truck. A generator and a radar antenna, which has lightweight Kevlar armor added for protection against small-arms fire and shrapnel, are towed behind the truck. Once placed, a single soldier can operate the Firefinder system.
