ERIEYE AEW&C Mission System

ERIEYE is a high-performance, long range Airborne Early Warning and Control (AEW&C) system based on active phased-array pulse doppler radar. The ERIEYE meets full AEW&C reqirements for detecting and tracking targets at ranges of upto 450 Kms over land or water. ERIEYE is part of a complete AEW&C system, including radar with integrated Secondary Surveillance Radar, Identification Friend or Foe (SSR/IFF) electronic support measures, communications and data links, comprehensive command-and-control facilities and self-protection systems. The ERIEYE radar with its fixed electronically scanned antenna and use of adaptive radar control techniques, has superior resolution accuracy. When compared to traditional rotodome based solutions, it provides enhanced detection and tracking performance, including the active simultaneous tracking of multiple targets. In addition, the radar offers significantly improved resistance to Electronic Counter Measures (ECM). The state-of-art command and control system gives the onboard mission-system crew full capability for AEW&C roles as well as maximum flexibility for other peacetime roles.

ERIEYE uses the multibeam adaptive array antenna. Due to microstrip patch elements, Butler matrices, and several dual-polarized beams, adaptive antenna arrays yield high antenna gain and excellent spatial efficiency.

The Ericsson Erieye system uses an active phased array radar mounted in a two sided array geometry contained in a large beam shaped structure carried above the fuselage. The limitation of the two sided array is that it can only cover two 120 degree sectors abeam of the aircraft, leaving 60 degree blind sectors over the nose and tail of the aircraft.
