Active electronically scanned array (AESA) radars are innately harder to jam and can operate in low probability of intercept (LPI) modes to reduce the chance that the radar is detected. A quantum radar system would automatically detect attempts at deceptive jamming, which might otherwise go unnoticed.
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 poor reliability of the ALQ-99 and frequent failures of the Built-In Test (BIT) have caused crew to fly missions with undetected faults. The ALQ-99 also interferes with the aircraft's AESA radar, reduces the top speed of the aircraft and imposes a high workload on the two-person crew when employed in the EA-18G Growler. [7]
Basic radar ECM strategies are (1) radar interference, (2) target modifications, and (3) changing the electrical properties of air. [1] Interference techniques include jamming and deception. Jamming is accomplished by a friendly platform transmitting signals on the radar frequency to produce a noise level sufficient to hide echos. [1]
The AN/APG-81 is an active electronically scanned array (AESA) fire-control radar system designed by Northrop Grumman Electronic Systems (formerly Westinghouse Electronic Systems) for the Lockheed Martin F-35 Lightning II. [1] The AN/APG-81 is a successor radar to the F-22's AN/APG-77, and has an antenna composed of 1,676 transmit/receive modules.
The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.
The AN/SPY-6 is an active electronically scanned array (AESA) [1] 3D radar system developed and built by RTX corporation, formally Raytheon, and in service with the United States Navy (USN). [2] It provides integrated air and missile defense for Flight III Arleigh Burke -class destroyers . [ 3 ]
The AN/APG-79 is a type of active electronically scanned array (AESA) radar that was developed for use on the United States Navy's Boeing F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft. [1]
