AN/MPQ-64 Sentinel – Advanced Short-Range Air Defense Radar

The AN/MPQ-64 Sentinel is a three-dimensional, phased-array radar system developed by Raytheon Technologies for the U.S. Army. Designed to provide short-range air defense (SHORAD) coverage, the Sentinel radar is a crucial component in protecting ground forces from low-flying aircraft, cruise missiles, and unmanned aerial vehicles (UAVs). Deployed worldwide, it forms the radar backbone for systems like Avenger, NASAMS, and Maneuver SHORAD (M-SHORAD).

Design and Capabilities

Operating in the X-band frequency, the AN/MPQ-64 offers 360-degree azimuth coverage and 3D target acquisition with automatic tracking of over 60 aerial targets simultaneously. Its electronically steered antenna allows fast beam agility and high precision, capable of detecting threats at distances up to 75 kilometers. The system uses solid-state transmitter technology, advanced signal processing, and electronic counter-countermeasures (ECCM) to perform effectively in contested environments.

Mounted on a high-mobility trailer or vehicle, the Sentinel radar provides rapid deployment and high survivability. It is integrated with the Integrated Air and Missile Defense Battle Command System (IBCS) for networked operations and real-time data sharing across the battlefield.

Operational Use

Since entering service in the 1990s, the Sentinel has supported numerous missions across Europe and the Middle East. It remains in continuous upgrade cycles, including the A3/A4 variants, which introduce improved range, AI-assisted classification, and digital beamforming.
