EMB-145 SA

Merging Embraer’s successful ERJ-145 regional aircraft platform with the Ericsson Erieye AEW Radar and Command and Control System, the EMB-145 SA (Surveillance Aircraft) also relies on a number of other sensors that give it multi-role capability. Besides AEW&C tasks the EMB-145 SA can also execute missions such as border surveillance and control, sea surveillance, search and rescue coordination, airspace management and signals/communications intelligence. The aircraft will be capable of integrating data in real-time with ground stations and other airborne elements. The EMB-145 AEW&C incorporates a reinforced airframe, new navigation and communication systems, an enhanced APU, increased fuel capacity and revised interior layout. The endurance in typical missions in the Amazon shall be in excess of 8 hours.

Performing its maiden flight on 22 May 1999, the EMB-145 SA Airborne Early Warning & Control (AEW&C) aircraft is configured to comply with the SIVAM Project requirements. With five units ordered by the Brazilian Government’s SIVAM (Amazon Surveillance System) Project and basis for the EMB-145 AEW&C aircraft selected by the Hellenic Air Force to fulfill its AEW&C requirements, the EMB-145 SA offers performance allied to systems and airframe availability. First delivery to the SIVAM Project is scheduled for June 2001.

The EMB-145 SA is an AEW&C optimized for air traffic control applications. It incorporates an advanced mission system that includes a surveillance radar, advanced navigation and communication systems including data-link facilities and increased fuel capacity. ERIEYE detects and tracks air and sea targets to the horizon and beyond. The ERIEYE AEW&C Mission System features a new generation active, phased-array pulse-Doppler radar and a modularly, open C2 system. It means a considerably step-up in performance over systems depending on conventional rotodome antennas, providing improved radar performance, and higher system availability and growth potential. The ERIEYE single, dual-sided fixed antenna unit places much less demand on aircraft size than was previously possible for high performance AEW&C systems. ERIEYE is the world’s first high-performance AEW&C system designed for commuter type aircraft. This has resulted in reduced acquisition as well as operational costs. ERIEYE detects and tracks air and sea targets out to the horizon and beyond. Instrumented range is 450 km. Typical detection range against a fighter size target is in excess of 350 km.

Embraer is also developing an Airborne Remote Sensing version that employs the same airframe but outfitted with different mission sensors. Designated EMB-145 RS, three of these aircraft systems were also ordered for the SIVAM Project.
