In contrast, the beam of a PESA radar can rapidly be changed to point in a different direction, simply by electrically adjusting the phase differences between different elements of the passive electronically scanned array (PESA). In 1959, DARPA developed an experimental phased array radar called Electronically Steered Array Radar (ESAR). It was ...
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
The radar's AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. [2] The radar has a range of up to 150 km (80 nm) and can track multiple targets simultaneously. [3]
The new radar is able to track 14 targets simultaneously while being able to simultaneously attack 6 of those. Raytheon delivered 180 APG-63(V)1 radar systems to the U.S. Air Force (4 of which have since been lost to crashes), and is on contract to deliver an additional 60 radars to the Republic of Korea Air Force for the F-15K Slam Eagle.
