AN/TPQ-64 “Sentinel”

AN/TPQ-64 “Sentinel” is operating in the X-band, 3D search and target acquisition pulse-doppler radar designed for SHORAD systems. AN/TPQ-64 is designed to spot incoming aircraft, drones, and cruise missiles from up to 40 kilometers away. It includes a Mode 5 identification friend or foe (IFF) subsystem. Sentinels are typically deployed with forward-area air defense units, like NASAMS.

The radar is trailer-mounted and pulled by either a High Mobility Multipurpose Wheeled Vehicle (HMMWV) or an M1082 Family of Medium Tactical Vehicles truck, fitted with a 10 kW 400 Hz 115/200 VDC on-board power generator. AN/TPQ-64 uses a phased array antenna that is folded down on the trailer for relocation. Due to its relatively light weight, 3 900 lbs (≙ 1 800 kg), it can be airlifted by helicopter and easily be put on rooftops or specially built towers for elevated radar coverage.

Sentinel is developed on the basis of AN/TPQ-36A mortar locating radar.
