SAAB S-100B Argus AEW |
)
The Erieye Radar System is being developed by Ericsson and SAAB to provide an AEW capability for the Swedish Air Force. The prototype of the PS-890 Erieye Electronic Scanned Array (ESA) Radar was first flown on a Fairchild Metro III (above), however the operational configuration being delivered to the Swedish Armed Forces from 1996 onwards is based on the SAAB SF340 Commuter Aircraft (below).
The completed operational system has been designated S-100B Argus by the Swedish Air Force, with six airframes planned to be in service by 1999. ESA Radars differ from Rotodomes or mechanically scanned systems as used on the Sentry or Hawkeye in that they have no moving parts, the beam being steered electronically by the phased array radar. Testing has begun on a variant of the Erieye based on the SAAB 2000 airframe, an artists concept being shown below. More recently the Erieye radar has been chosen as part of the Surveillance of the Amazon system for Brazil, being fitted to the Embraer EMB 145 regional jet aircraft as shown in the concept picture at bottom, with five systems on order as part of the project. Wind tunnel testing of this configuration was completed in November 1996.
