Raytheon To Support US Army’s Radar System Used To Alert SHORAD Weapons
Sentinel Radar System

Raytheon has won a $160.8 million contract to support the US Army’s Sentinel Radar System, which is used to alert and queue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces.

According to the statement released by the US Department of Defense on Wednesday, Raytheon will provide engineering and technical services to support the Sentinel Radar.

The antenna of the Sentinel uses phase-frequency electronic scanning technology, forming sharp 3D pencil beams covering large surveillance and track volume. The radar automatically acquires, tracks, classifies, identifies and reports targets, including cruise missiles, drones, and both rotary- and fixed-wing aircraft. It uses a scan rate of 30 RPM and operates at a range of 40 km (25 miles). The radar is designed with high resistance to electronic countermeasures (ECM).
