SAAB Erieye, a 'Game Changer' in Modern Air Combat
The Erieye Airborne Early Warning and Control (AEW&C) aircraft, which uses an active electronically scanned array (AESA), was developed by Saab Electronic Defence Systems (formerly Ericsson Microwave Systems) of Sweden. The Erieye radar system has been used on several aircraft types, such as the Saab 340 and Embraer R-99. It was recently deployed on the Bombardier Global 6000 aircraft as Globaleye.
The Erieye radar can detect up to 300 degrees, has an instrumental range of up to 450 km, and a detection range of up to 350 km. In dense, hostile electronic warfare environments and heavy radar clutter with low-altitude targets, this radar can identify friend or foe.
The Erieye system is fully interoperable with NATO air defense command and control systems.
PS-890 Erieye
The Saab Microwave Systems Erieye is an airborne early warning and control (AEW&C) system based on an active phased array pulse Doppler radar. It can be installed on a wide range of commercial and military jet or turboprop aircraft. It detects and tracks airborne targets at ranges of up to 300/450 km over land or water and from low altitudes up to 82,000 feet. It consists of an IFF, ESM, communications, C2 workstation, self-protection system, and integrated data link to provide AEW&C capabilities.
The PS 890 “Erieye” (short for “Ericsson eye”) is a side-looking airborne radar integrated into the Airborne Early Warning and Control (AEW&C) system developed by Saab Electronic Defence Systems, formerly Ericsson Microwave Systems, of Sweden. The system operates in the S-band (IEEE designation) or the E/F-band (NATO designation).
The antenna is a non-removable active electronically scanned array (AESA) that uses 192 transmitter and receiver modules. This radar is a pulse-Doppler system and provides 2 x 120-degree coverage to altitudes exceeding 65,000 feet (≙>20 km) in the broadside sector, covering both sides of the aircraft. The first radar was delivered in 1996.
The Erieye radar has a fixed electronically scanned array antenna that provides superior resolution to rotodome radars. It tracks multiple targets simultaneously and is highly resistant to countermeasures. Typically, the radar antenna is mounted on the upper fuselage of a carrier aircraft, which can be a turbofan or turboprop.
The Swedish Air Force operates the Erieye radar system on its Saad 340B turboprop aircraft. Aircraft equipped with the Erieye radar are called Argus. In October 2005, Pakistan ordered Erieye radars integrated into Saab 2000 turboprop aircraft. Greece and Brazil ordered Erieye radars integrated into EMB-145 turbofan-powered aircraft, also known as EMB-145 Erieye. In 2007, Thailand ordered Erieye AEW&C systems integrated into Saab 340Bs.
Erieye ER extended range
Erieye ER is an extended-range version of the Erieye surveillance radar developed by Saab for Airborne Early Warning and Control (AEW&C) aircraft. Erieye ER enables simultaneous long-range detection, tracking, and reconnaissance of air, ground, and sea targets in highly crowded and cluttered environments. The radar provides wide-area moving target indication (GMTI) as well as improved performance against small targets such as stealth aircraft, drones, cruise missiles, or submarine periscopes.
