Some questions about 'Fazotron's AESA are resolved on MAKS-2009

The comparative estimations of AESA radars became very popular in the discussions on different military fora. It becomes even more important in view of Indian MMRCA tender, where AESA radar existence is seemingly an ultimate condition for win. Last time the question was raised about Russian 'Zhuk-AE' radar capabilities. This radar is offered with MiG-35 fighter for Indian MMRCA competition too. In its initial 680 MMICs 'avatar' it was displayed with the main characteristic of 120 km detection range for standard flying targets (enemy fighter with 3 m2 RCS). However, the last information, published by a Russian new agency in August 2009 just before MAKS-2009 Air Show, contradicts to this figure. Then was pointed to 148 km of effectively detected and tracked air targets.


Fortunately, being on MAKS-2009 in August 21, I have met 'Fazotron-NIIR's chief constructor Anatoly Kanashchenkov near 'Fazotron's stand.

I must say it in no mean was official interview, but he answered for all my questions with pleasure. I was impressed by his openness and friendliness. He explain me, that initially figured 120 km detection range – is highly downplayed, and reflect the real capability of the radar in very initial stage of work, already overcome. According to him, the planned capability of standard flying target detection for Zhuk-AE (with 680 emitting units) is 250 km, and he is in no doubt to achieve it.

Unlike MAKS-2007 this year only  'Zhuk-AE' dummy was displayed. Mr. Kanashchenkov said me it's because all working AESAs are in active flying tests now.
I asked him whether he plans to go to the 'second generation' gallium-nitride technology for MMICs instead of current gallium-arsenide. Gallium-nitride MMICs could give more powerful emission. He answered me, that it would be needed only if the electric power station of contemporary fighters was much more powerful. Now it limits the radar power, not the MMIC's technology. For example, he says, each 'Zhuk-AE's emitting element has 5 watt maximal output. However, now they still use only 3-3.5 watts with more output will be tested in the future. In addition, he explained me, Russian MMIC technology is better in some aspects, than other countries have. Russian MMICs are truly monolithic nanoheterostructures, while other AESA developers use soldered circuits with lesser reliability. Therefore, they also have no intention for 1000 units AESA for MiG-35 variant of the radar because 680 MMICs 'Zhuk-AE' is far from its full capabilities.

In addition, he said they actively work on EW, ELINT and net-centric capabilities of the radar. A popular question was about capability of AESA radar to disseminate computer viruses on enemy radars. He said it could be possible only if the enemy radar has OEM chips with a backdoor 'bug' installed. Then you can just give the command for enemy radar die-out via your AESA.

Француски Thales.
Делује сјајно. Штета што нема пуно информација о њему.
Ови "штапићи" што вире су вивалди антене које омогућавају радару велики фрекфентни опсег што је веома важно. Руси за сада нису приказали своје вивалди антене премда је Фазатрон још пре 2 године рекао да раде на њима.

ima dosta podataka o thalesovim mornarichkim AESA radarima ,a o ovom RBE" nadjoh ovo :

Хвала.

Негде сам прочитао да су првих 4 предпродукцијских примерака RBE2 платили 200 милиона евра.
Развој овог радара је завршен и од следеће године Рафал испоручују са овим радаром.

Иначе RBE2 има око 1000 модула на антени што је одличан број. (Руски Жук-АЕ има 680, руски ПАК-ФА има 1526)

to je verovatno ovaj chlanak :

AESA Radar

While the first 100 or so Rafales were fitted with the early Thales RBE2 radar, the most important sensor of the next generation Rafale will be the new Thales RBE2 AA active electronically scanned array (AESA) radar, which will replace the passive array of the RBE2.

Thales completed its first active phased array, comprising 1,000 gallium-arsenide Transmit/Receive modules, in 2006. In late April this year, the company said the RBE2 AA had successfully completed a new series of tests on Rafale, carried out jointly with the French DGA defense procurement agency, at the Cazaux flight-test center.

"This milestone marks the latest step toward qualifying the RBE2 AESA radars this year in readiness for delivery of the first two units to Dassault Aviation during the first quarter of 2010," Thales stated. "The radars will be installed on the aircraft in 2011 for delivery to the French Air Force early in 2012."

In operational terms, the RBE2 AA radar can track many targets in the radar field of view irrespective of the relative location between targets and/or the host aircraft. In addition, the radar provides a significant increase in detection range on enemy aircraft and a significant increase in reliability with respect to previous-generation radars.

Since the AESA radar antenna comprises a very large number of active modules, the failure of some of these modules has no noticeable effect on the overall performance and reliability of the system. Consequently, the active front end only requires maintenance every 10 years or more, thereby contributing to increased aircraft availability and reducing replacement part costs.

The RBE2 is a track while scan, monopulse-doppler X-band multimode fire-control radar system built around a modular concept. Air-to-air tracking and air-to-ground mapping functions can be interleaved due to the radar’s agile beam sweeping capabilities.

Fitted in the aircraft’s pointed nose, the RBE2 provides +/- 60 degree azimuth and elevation coverage and includes the SB-25A MkXII compatible IFF interrogator/transponder with Mode S capability. The IFF system uses phased array antennas just like the Spectra active electronic countermeasures (ECM) antennas.

The present radar air-to-air modes include long-range search; multi target track and engagement; air combat modes; Non-Cooperative Target Recognition (NCTR); and look down/shoot down functions. In air-to-air mode, the RBE2 gives a tracking range beyond 60 nautical miles against a 30-square-foot target, with detection ranges up to 75 nautical miles. The radar can track and prioritize up to 40 targets simultaneously and engage up to eight with Mica, and soon Meteor, air-to-air missiles.

The RBE2 air-to-ground modes include: Doppler Beam Sharpening (DBS) mapping; SAR mapping; Fixed Target Track (FTT); Sea Surface Search and Track While Scan; Ground Moving Target Identification and Track (GMTI/T); target acquisition and air-to-ground ranging. Terrain following and avoidance modes can be combined to generate 3-D radar maps, thus enabling full automatic terrain following flights using the radar only.

Хвала.

Дакле према том чланку параметри за RBE2
за циљ површине 2.8 квадратних метара су за:
детекцију: 140 км
праћење и дејство: 112 км


Руски Жук-АЕ  циљ површине 3 квадратних метара прати већ на 148 км, (на врху стране пише) а притом Руси тврде да ће догурати до 250 км, дакле или Французи имају лошији радар или неће да открију праве могућности. 

Ја ипак мислим да неће да открију праве могућности.

Prema poslednjim saznanjima jednog prijatelja koji prati dešavanja u Brazilu, Sarkozi je uspeo da potpiše prvi ugovor o prodaji Rafala. Prvi primerci se očekuju 2014. a ovo pišem ovde upravo zbog toga što će ovi avioni biti opremljeni novim radarom. Inače isti radar je trebao da ima i Gripen, ali pošto su bili konkurencija na tenderu FX-2 za brazilski višenamenski avion, Dassault je kupio paket akcija Thalesa i otkazao ugovor sa šveđanima koji su bili prisiljeni da potraže saradnju sa firmom SELEX Galileo i sa njim azajednički razvijaju AESA radar za JAS 39NG.
Malo više o tome OVDE.

Није лоше, није лоше, корисно и за Француску и за Бразил. 

Још једна важна вест:
Фазатрон Жук-АЭ AESA је завршен и спреман за борбену употребу на МиГ-35 чиме је испуњен један од услова индијског тендера за набавку нових авиона.

Даљина праћења је 148 км на 70% снаге радара.
Радар има 680 елемената.

Извините што поново активирам тему али је сасвим природно да наставим овде због прегледности и наставка низа вести тако да чланови могу да прате хронологију развоја радара.

Дакле у 2010. години су Руси произвели 10 радара типа Жук-АЕ (AESA) за авионе типа МиГ-29К, МиГ-СМТ и МиГ-35. Такође су модификовали партију радара са бивших алжирских МиГ-29 на руски стандард. Дакле са Жук-МЕ на Жук-М. (Оно "Е" значи експортни.)
(То су они враћени авиони за оне који не знају.)
