AESA radar http://www.youtube.com/watch?v=XIm59P5BNSQ An Active Electronically Scanned Array (AESA), 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 (TRMs). AESAs aim their "beam" by broadcasting radio energy that interfere constructively at certain angles in front of the antenna. They improve on the older passive electronically scanned radars by spreading their broadcasts out across a band of frequencies, which makes it very difficult to detect over background noise. AESAs allow ships and aircraft to broadcast powerful radar signals while still remaining stealthy. |

South Korea Launches KF-16 Fighter Fleet Upgrades May 08, 2014 17:16 UTC by Defense Industry Daily staff In July 2009, The Korea Times reported that ROKAF was looking to upgrade its F-16C/D fleet’s radar and armament, as part of the 2010-2014 arms acquisition and management package submitted to President Lee Myung-bak for approval. Under the Peace Bridge II and II deals, The ROKAF bought 140 “KF-16″ Block 52 fighters, which were assembled in Korea between 1994-2004 under a $5.5 billion licensing agreement. Key upgrades to this fleet will include new radars to replace the existing APG-68v5/v7 systems, modern avionics and computers, and upgrades of the planes’ cabling and databuses to MIL-STD-1760. The centerpiece AESA radar competition has a winner now, and South Korea has picked its contractor for the overall upgrade program. Now the effort is turning that into binding contracts, and beginning the upgrade process. Other countries within the region and beyond are interested in similar high-value F-16 upgrade programs, so the ROk’s experiences will be watched carefully. Korea’s KF-16 Radar The Benefits of AESA Technology Active Electronically Scanned Array radars offer dramatic increases in fighter performance, and an equally dramatic drop in maintenance costs, thanks to their large array of independently excitable and steerable transmit/receive modules. Advantages over mechanical phased array radars like the KF-16s’ APG-68 include 2x-3x range or performance, simultaneous ground and air scans, and near-zero maintenance over the fighter’s lifetime. The fixed AESA antenna in American designs cuts out high-maintenance motors and hydraulics, and if one T/R module out of thousands burns out or breaks, it matters so little that it’s just left on. More advanced functions like high speed communications, and even focused electronic disruption of enemy radars, also become possible. South Korea was very interested in AESA performance, but we were told by contractor sources that their calculations of the long-term maintenance savings over existing mechanically-scanned APG-68 radars helped them decide to make the investment in AESA. F-16s have several AESA radar versions to choose from. Northrop Grumman supplies the AN/APG-68 radars that equip most current F-16s, as well as the AN/APG-80 radar that equips the United Arab Emirates’ F-16E/F Desert Falcons. The firm has gone on to develop a more generic AESA system called SABR (Scalable Agile Beam Radar) as a drop-in AESA replacement for existing F-16 radars like the APG-68. Raytheon has taken similar steps, developing an AESA radar called RACR (Raytheon Advanced Combat Radar) for the same purpose. Their radar won, and will equip up to 134 KF-16s. A 3rd possible choice is IAI ELta’s EL/M-2052 . It was originally developed for Israeli F-16s, and would probably have been fitted to the F-16I if the USA hadn’t threatened to cut of all manufacturer support for the fighters. This raises the specter that the US government would use the same tactics in export competitions, so perhaps it’s not surprising that the M-2052′s most promising sales prospects currently involve non-American fighters in India. AESA After-Effects Korea Aerospace Industries has a very broad set of cooperation agreements with Lockheed Martin, from licenses to build and maintain the ROKAF’s F-16s, to the T-50 family’s development and international marketing agreements. One of those agreements states that the T-50 family of trainers and lightweight fighters may not be equipped with radars more sophisticated than the ones carried in the ROKAF’s KF-16s. That clause is what forced KAI to abandon SELEX’s Vixen 500E AESA radar for the FA-50, and select IAI Elta’s EL/M-2032 mechanically-scanned radar instead. Adding AESA radars to the KF-16s would remove those strictures, opening the door for similar additions. The result would be a $30-35 million AESA-equipped FA-50+ lightweight fighter for the global export market, which could be a strong competitor for existing F-16s at $40-55 million each. It could even affect broader F-35 exports (currently $120 million per), thanks to its combination of advanced capabilities and traditional lightweight fighter price. http://www.defenseindustrydaily.com/south-korea-looking-to-upgrade-its-kf-16s-05404/ |
