The RBE2-AA radar system is an [[active electronically scanned array]] (AESA) radar system derived from the Rafale's RBE2 radar. It replaces the mechanically steered array antenna by electronically steering exerted by up to several thousand of transmit-receive modules which enable maximum performance and versatility as well as enhanced reliability. The improved RBE2-AA radar system is available since 2012 for the Rafale fighter-aircraft owned by the French Air Force, Navy and export customers. |

The RBE2 (Radar à Balayage Electronique 2 plans) is a multirole radar developed during the 1990s for the Dassault Rafale, a French combat aircraft. The original RBE2 is a passive electronically scanned array. This has since been developed into the RBE2-AA, an active electronically scanned array.
Development
[edit]Development of the RBE2 began in 1989 as a joint project between Thomson-CSF's RCM division and Dassault Electronique which merged in 1998 to form Thomson-CSF Detexis.[1] Development was continued by Thomson-CSF's successor company, Thales Group.[2]
The RBE2 is a passive electronically scanned array (PESA), an electronically scanned radar with a single transmitter. Flight trials of the RBE2 began in 1992 and the first production radar was delivered in May 1997.[3][4]
In April 2002, the French defence procurement agency, Délégation Générale pour l'Armement (DGA), awarded Thales Group a contract to develop an active electronically scanned array (AESA) radar demonstrator based on the RBE2 radar. The resulting RBE2-AA (active array) variant has been tested on a Mirage 2000 testbed aircraft from the Flight Test Center of the DGA and then on a Rafale. While the first tests were made with US-made transmitter-receivers, the current radar features parts manufactured by Thales. The radar uses about 838 GaAs T/R modules.
In July 2004, DGA awarded a 90 million-euro contract for the development of a second a AESA radar demonstrator. Production of the RBE2-AA commenced in 2008 and entered service in 2013.[5][6]
