English: The AN/TPQ-37 Firefinder is a highly mobile counter-fire radar designed for automatic first round location of hostile rounds. The system tracks the enemy fire, then the coordinates are interfaced to a tactical fire control center that directs counter fire. The radar detects in-flight projectiles, determines and communicates firing point locations of mortars, artillery and rockets with a high degree of accuracy and classifies the hostile fire weapon’s location. It provides early warning of incoming fire and allows for the direction of the counter-fire in the C-RAM construct. AN/TPQ-37 also tracks friendly rounds and provides impact prediction, registration and fire adjustment information to the fire control center.
