Erieye Radar in layman's language
The Erieye radar system is an Airborne Early Warning and Control (AEW&C) system developed by Saab Microwave Systems of Sweden. It is based on an Active Electronically Scanned Array (AESA).
The radar is an active, phased-array, medium to high PRF pulse Doppler sensor that can feed to on-board operator architecture or downlink data.
Its antenna is fixed and the beam is electronically scanned, which provides superior detection and significantly enhanced tracking performance compared with older style radar-dome antennas.
The radar provides a broadside sector of 150º on each side and has an instrumental range of 280 miles (450km). It works from low level up to more than 82,000ft (25,000m) and has an effective surveillance area of 193,000 sq. miles (500,000km2). The system can track 500 sea and 1,000 air targets simultaneously, identified either manually or automatically.
For example, the radar can detect/track air targets, sea targets and hovering helicopters simultaneously in a split second. This is applied in a dense hostile electronic warfare environment, in heavy radar clutter and at low target altitudes. It detects small air targets, hovering helicopters, cruise missiles and small sea targets such as jet skis etc. It works in E/F band (3GHz) incorporating 192 two-way transmit/receive modules.
The Erieye system has full interoperability with NATO air defense command and control systems and other LINK 16 equipped assets.
