AN/TPQ-36 Firefinder radar

Hughes AN/TPQ-36 Firefinder weapon locating system is a mobile radar system developed in the mid-late 1970s by Hughes Aircraft Company and manufactured by Northrop Grumman and ThalesRaytheonSystems, achieving initial operational capability in May 1982. The system is a "weapon-locating radar", designed to detect and track incoming mortar, artillery and rocket fire to determine the point of origin for counter-battery fire. It is currently in service at battalion and higher levels in the United States Army, United States Marine Corps, Australian Army, Portuguese Army, Turkish Army, and the Armed Forces of Ukraine.[1]

The radar is typically trailer-mounted and towed by a Humvee.


Firefinder (V)7 adds a modular azimuth position system (MAPS). MAPS has a north seeking laser gyrocompass and a microprocessor controlled Honeywell H-726 inertial navigation system. Prior Firefinders used a survey team to find site latitude, longitude, and direction to North. With MAPS, reaction time was limited only by the time taken to set up the site, since system geo-position was pre-loaded before sortie deployment. Crew was reduced from 8 to 6.[2]

Firefinder (V)8 extends system performance, improves operator survivability and lowers life cycle cost. Greater processing power and the addition of a low noise amplifier to the radar antenna improves detection range (by up to 50%) and performance accuracy against certain threats.

The AN/TPQ-36 is an electronically steered radar, meaning the radar antenna does not actually move while in operation. The radar antenna may however be moved manually if required. The system may also be operated in a friendly fire mode to determine the accuracy of counterbattery return fire, or for conducting radar registration or mean point of impact calibrations for friendly artillery.

It can locate mortars, artillery, and rocket launchers, simultaneously locate 10 weapons, locate targets on first round and perform high-burst, datum-plane, and impact registrations. It can be used to adjust friendly fire, interfaces with tactical fire and predicts the impact of hostile projectiles.

Its maximum range is 15 miles (24 km) with an effective range of 11 miles (18 km) for artillery and 15 miles (24 km) for rockets. Its azimuth sector is 90°. It operates in the X-band at 32 frequencies. Peak transmitted power is 23 kW, min.

It features permanent storage for 99 targets, has a field exercise mode and uses a digital data interface.


Northrop Grumman manufactures the AN/TPQ-36(V)8 Firefinder radar. Before its acquisition by Raytheon, the Hughes Aircraft Co. developed the AN/TPQ-36 Firefinder radar at its facility at Fullerton, California, and manufactured it at its plant in Forest, Mississippi.


Per the Joint Electronics Type Designation System (JETDS), the nomenclature AN/TPQ-36 is thus derived:
