aircraft, providing a high level of aircrew situational awareness. The beam of the AESA radar provides nearly instantaneous track updates and multi-target tracking capability. The APG-79 AESA uses transmit/receive (TR) modules populated with GaAs MMICs. In the F/A-18E/F, the radar is installed in a slide-out nose rack to facilitate maintenance.
The APG-79 features an entirely solid-state antenna construction, which improves reliability and lowers the cost compared to a traditional system. The radome of the APG-79 for the F/A-18E/F slides forward instead of hinging to the right, which saves space in aircraft carrier hangars.
The APG-79 is compatible with current F/A-18 weapon loads and enables aircrew to fire the AIM-120 AMRAAM
, simultaneously guiding several missiles to several targets widely spaced in azimuth, elevation or range.
The APG-79 radar completed formal operational evaluation (OPEVAL) testing in December 2006. As of January 2007 the radar was installed in 28 aircraft; some were experiencing software problems but that issue was expected to be resolved by the end of fiscal year 2007. As of July 2008, Raytheon
had delivered 100 APG-79 sets to the Navy; on June 3, 2008, the Navy received the first APG-79-equipped EA-18G Growler
. The Navy expects to order approximately 400 production radars.
Active Electronically Scanned Array
An Active Electronically Scanned Array , also known as active phased array radar is a type of phased array radar whose transmitter and receiver functions are composed of numerous small solid-state transmit/receive modules . AESAs aim their "beam" by broadcasting radio energy that interfere...
