AESA雷达中的频率弹性和混合抗干扰能力:来自固态-半模块的优势

The superiority of active phased array radars in the frequency domain Active Electronic Scan Array (AESA) is a type of phased array radar in which each module on the antenna emits radio waves separately, directing its beams in a way that creates constructive interference in front of the antenna. Advanced AESA radars can emit waves over a wider frequency range than passive electronic scan arrays (PESA), making them harder to detect through background noise. This allows ships and aircraft to remain more covert even when emitting strong radar signals.

The first AESA on an aircraft was used in the Mitsubishi F-2 in 1995, and the first AESA on a missile was developed for the AAM-4B air-to-air missile, carried by the Mitsubishi F-2 and the McDonnell-Douglas F-15J. Among the AESA radars currently in use are the AN/APG-77 developed by Northrop Grumman and used on the F-22 Raptor aircraft, and the AN/APG-81 developed by Northrop Grumman and used on the F-35 Lightning II aircraft. The AN/APG-79, developed by Raytheon, is used on the F/A-18E/F Super Hornet and EA-18G Growler aircraft, while the AN/APG-82(V)1 is used on the F-15E Strike Eagle aircraft. The Captor-E CAESAR, developed by Raytheon, is used on the Eurofighter Typhoon aircraft, while the RBE2-AESA, developed by Thales, is used on the Rafale fighter aircraft. The J/APG-1/J/APG-2, developed by Mitsubishi Electric Corporation, is used on the Mitsubishi F-2 fighter aircraft, while the EL/M-2052, developed by Elta Systems, is used on various aircraft, including the Sukhoi Su-30MKI of the Indian Air Force. The EL/M-2075, developed by Elta Systems, is used in the IAI Phalcon AEW&C system, while the Zhuk-A/AM, developed by Phazotron NIIR, is an option for the MiG-35 aircraft.
