The Erieye radar system is an Airborne Early Warning and Control System (AEW&C) developed by Saab Electronic Defence Systems, formerly Ericsson Microwave Systems, of Sweden. It uses active electronically scanned array (AESA) technology. The Erieye is used on a variety of aircraft platforms, such as the Saab 340 and Embraer R-99. It has recently been implemented on the Bombardier Global 6000 aircraft as the GlobalEye.

The Erieye Ground Interface Segment, EGIS, not to be confused with the Aegis combat system, is a major component of the software used by the Erieye system.

The radar provides 300 degree coverage and has an instrumental range of 450 km and detection range of 350 km in a dense hostile electronic warfare environment—in heavy radar clutter and at low target altitudes. The radar is capable of identifying friends or foes, and has a sea surveillance mode.

The Erieye system has full interoperability with NATO air defence command and control systems.
