OVERVIEW: The Plessey AR-3D is a transportable, long range, 3-D air defense radar operating in the E/F Band.
DETAILS: The AR-3D uses a planar-array antenna with frequency steered pencil beam groups to electronically scan in elevation. The system is highly automated. ECCM capabilities include frequency scanning in elevation and electronic antenna-tilting. Additionally, its narrow radiated beam, low sidelobes allow it to operate effectively in an ECM environment.
Frequency: 2.9-3.1 GHz (E/F Band (NATO), S Band (IEEE)) Power output: 10 kW(average); 1.1 MW (peak) PRF: variable Range Accuracy: 18 m (range), 0.16 degrees azimuth On/Off time: unknown Deploy/Stow Time minutes/ minutes
Detection Range (2m2 target)(max): 556 km
NOTES: IOC 1975.Users include Egypt, South Africa, Great Britian, Quatar and Ecuador
