RADAR

The antenna systems for primary radar and the Information Friend or Foe (IFF) interrogator are mounted in a 9.1m diameter circular radome above the aircraft fuselage. The primary radar is the AN/APY-2, developed for E3 AWACS by Northrop Grumman in Baltimore. The radar operates at about 10GHz (wavelength about 10cm) in the E/F bands. It scans mechanically in azimuth at six revolutions per minute, and electronically in elevation. In flight, when the radar is not operational, the slip rings and bearings are kept lubricated by rotating the radome at one cycle per four minutes.

The main modes of operation of the radar are: pulse Doppler non elevation scan; pulse Doppler elevation scan; beyond-the-horizon mode; maritime mode for detection of surface ships; combined operational modes using data interleaving for long-range detection; and passive mode operation in which the transmitters are switched off for radar-silent operations.

The AWACS radar provides a 360-degree view of the area. At operating altitudes it can detect targets more than 320km away. Targets are separated and individually managed and displayed on situational displays.
