 Based on an Active Electronically Scanned Array (AESA) radar and antenna, the Phalcon fuses data from the radar, but also IFF, COMINT and ELINT sensors.When the supplemental sensors detect an item of interest, the system control computer begins an active search for more information from other on-board and ground-based sensors.First exhibited in 1993, full Phalcon, other than one on an Israeli 707, has been sold to Chile and India (Ilyushin Il-76 platform), although a sale to the People's Republic of China was blocked by the US.
