    After rafale had been declared the winner of MMRCA deal there were many angry reactions coming from many self proclaimed
    defence experts & arm chair generals in india that Rafale's puny radar wont be able to give IAF any edge in future aerial combat & IAF would be losing it's combat edge against it's adversary.But people dont understand that RBE 2 AESA radar was the safest bet for IAF in comparision to all MMRCA contenders AESA radar's at that time
    & would be in future also .


    This article tries to explain why RBE 2 AESA radar was the safest bet for IAF in MMRCA evaluations??

    1st we should know what was the MMRCA radar requirement at that time??

    MMRCA RADAR REQUIREMENTs

    1) MINIMUM DETECTION RANGE FOR AN AESA RADAR

    One of the selection criteria in the tender is that the fighter's radar must have an active phased array radar with a target detection range of at least 130 kilometers (about 80 miles)."

    Zhuk-AE X-band AESA radar offered to India ~ ASIAN DEFENCE


    2) DEMONSTRATION OF ATLEAST WORKING AESA MODEL IF NOT OPERATIONAL
    But what about the crucial AESA (active electronically scanned array) radar, which is operational only on American fighters at present? MoD said the ASQRs did "not require a flying AESA radar''. Instead, vendors had to demonstrate "a baseline radar model in flight or on a test-bed, the complete working model in a lab and how it would be integrated'' on the Indian MMRCA. "Five fighters, including Rafale and Typhoon, met this requirement,'' said the source.

    India goes full steam to finalize $10.4bn jet deal - The Times of India

    So for comparitive basis We would be stressing more on Air to air capabilities meanwhile ignoring the Air to ground capabilities of all the radars available at that time.





    SO 1st get started by taking a brief look about RAfale"S RBE 2 aesa RADAR & it's capabilities .

    RBE 2 AESA radar

    The french rafale at that time of MMRCA evaluations had fielded a prototype of RBE 2 aesa radar as it was not operational at that time .


    a)No of T/R modules ~ Approximately around 1000 T/R modules according to thales .

    SOURCE
    http://www.defense-aerospace.com/dae...mg/fox3_11.pdf

    The exact T/R module count is though classified . There were speculations of around 840/870 T/r module by seeing some pictures on net but those pics are not the real production RBE -2 AESA model but rather they are dummy models displayed during Le bourgett air show. Infact French dassault deliberatley shows the blurred production RBE -2 AESA model pics in the net & brochures to prevent exact T/R module count.

    b)DETECTION RANGE Against fighter size target = 180-190km (ESTIMATED) maximum range around 200km

    RBE 2 pesa has a detection range of (75 nautical miles) 130/135 km & tracking range beyond 60 nautical miles for a target 3m2 (fighter size target)

    source Avionics Magazine :: Serious Squall


    but French DGA claims RBE 2 aesa radar range is increased by 50% compare to PESA radar
    https://customeronline.thalesgroup.c...tes-new-series

    & some even claim almost twice the detection range of RBE pesa radar

    Delivery of Rafale C n°137, the first European combat aircraft equipped with an active phased array radar

    though if we take those claims then increase by 50% detection range of RBE 2 PESA radar it equals around 190/195km against a 3m2 target & if we take almost double claim then it's 200+ km range against a fighter size 3m2 target

    Though it is estimated to have maximum range around 200km if we trust French version of wikipedia of rafale & refer it's citations about those claims

    c) maximum no aerial target it can track=40

    FUTURE PLANS
    ....In the longer term, Thales plans to develop a conformal AESA radar featuring ultra-thin, lightweight antennas and very fast data links that could greatly increase the integration of onboard systems and permit them to fuse data and perform a host of new missions at an affordable cost. ......

    ...The ultimate aim is to develop a multipurpose conformal array with a shared common aperture that could be distributed all over the fuselage and wings without significantly affecting aircraft aerodynamics. This will take 10-12 years, Chaltiel says, meaning it could be available for the Rafale F4 standard, which is expected to be introduced around *2020, or the Mid-Life Update, planned for 2025-30......

    .....Moreover, the new design will be based on a patented “cloud transmit/receive module” (TRM) approach that will allow novel technologies such as gallium nitride modules to be inserted without changing the overall radar architecture or requiring full requalification.....

    Aviation Week & Space Technology | Jul-12-10 | Inside | Zinio Digital Magazines

    That means enhanced angular coverage ( conformal arrays on fuselarge or wings) + greater detection range of aerial targets thanks to GaN (5 times more powerful than current GaAS) T/R modules


    Drawback of RBE 2 AESA radar
    It has a limited angular coverage (foV) due to it's fixed aesa plate design compare to Swashplate aesa radars which have wider angular coverage (FoV) .So in a bvr warfare scenario after EM guided missile has been launched from rafale against a plane having a swashed plate or fixed plate array , the rafale cannot manuveur more than 70 degree from the viewing angle in comparision to swash plate aesa radar planes which have more than 90 degree FOV .
    So that means rafale would be closing in against those fighters which has a swash plate aesa radar or fixed plate aesa radar & meanwhile planes having swash plateaesa radar would be flying perpendicular or away from the rafale's BVR missile during it's evasion course but it would still be able to provide midcourse updates to it's own launched BVR missile .That could
    make rafale more prone to enemy fighters BVR missile attack.


    But according french Air&Cosmos 2355 issue defence magazine MBDA, Thales and Sagem started future Mica NG where provision has been included for third party targeting also in which wingmen / buddy rafale which is in active mode can also provide mid course updates to mica missiles launched by shooting rafale from a safe distance through (Mini awacs concept) .So the shooting rafale plane can easily move away from after launching BVR missile to it's target.





    Also after inclusion of conformal radar arrays in future this would also increase the angular coverage of RBE 2 aesa radar even further & negate the disadvantage of fixed plate RBE 2 aesa radar


    Meanwhile lets take a brief look about the capabilities of other AESA radar available during MMRCA evaluations & indian perspective regarding those aesa radar during MMRCA evaluations at that time

    1) MiG 35's ZHUK-AE AESA radar

    [​IMG]

    The Russian side have two variants of ZHUK-AE aesa radars one is FGA-29 model & other is FGA -35 model .During the evaluations they have fielded FGA 29 model but have claimed the FGA -35 model would be the real radar for MIG 35 in future.

    a)No of T/R modules
    Zhuk-AE' – FGA-29 model

    T/R modules=652
    Phazotron Zhuk AE: Assessing Russia's First AESA

    'Zhuk-AE'FGA -35 model
    T/R modules=1064

    b)DETECTION RANGE Against fighter size target 3m2

    'Zhuk-AE' – FGA-29 model
    130 km (head on) in both look-up or look down modes.
    Look-up tail-on detection range is 50km (40km look down).

    COMPARISION TO RBE 2 AESA radar
    definitely RBE 2 aesa radar out performs Zhuk ae 29 model in every thing but ZHUK AE 35 model was going to be the real radar
    of MiG 35 .Zhuk ae 35 radar has almost equal detection range or slightly higher .But it has higher no of aerial targets scanned compare to RBE 2 aesa radar.

    Indian perspective

    The IAF were not impressed by the performance of FGA-29 model basically they wanted a more powerful radar .
    Engines and radar to blame for MiG-35 failure in MMRCA contest - 8/4/2011 - Flight Global

    Also the Russians had not shown the FGA 35 model at that time it was in sketches only .They displayed it 1st time during MAKS 2013 airshow basically .Had they demonstrated it little earliear during MMRCA evaluations it would have made an impact .Not only that Mig 35 was not inducted by russian airforce by that time .One could be easily skeptical to beleive those claims whther the russians would indeed deliver on their promises.Still critics also claimed T/R modules MMIC technology which the russians have is inferior to western standards may be IAF didnt have beleive that russians can field an AESA comparable to western standards

    But none the else it's performance would also have been more or less equal to RBE 2 aesa radar in detection range .No major diffence would have happen even if they had demonstrated during evaluations.



    2)F16(IN) block 60 APG 80 aesa radar
    [​IMG]

    http://www.mycity-military.com/thumb...1959_apg80.jpg

    The Northrop Grumman APG 80 AESA radar was one of the only fully developed integrated AESA radar that is operational during the intial MMRCA trials


    a)No of T/R modules =1000

    source

    Active Electronically Steered Arrays - A Maturing Technology


    b)DETECTION RANGE Against fighter size target (3m2) =120-125 miles (210-215km)
    Source
    Actual radar range is classified and depend on the target and altitude. But roughly, the F-16 upgrade will likely come in at 125 mi. or slightly less.
    Raytheon and Northrop Grumman battle over F-16 radars

    it's has a range of 70-80 miles for a 1-sqm target according to (AW&ST 03/13/00)

    SOURCE
    Look-up detection range of the AN/APG-66/68 radar family
    so for 3sqm target it should be higher for sure around 120-125 miles (210-215km) or slightly higher than that





    c) Maximum no of aerial targets tracked & engage simultaneously
    Maximum aerial targets tracked=20
    maximum aerial targets engagement simultaneously=6

    Source

    Northrop Grumman Electronic Systems developed the AN/APG-80 Aesa radar for the F-16E/F fighters ordered by the United Arab Emirates. This has a greater detection range than the mechanically scanned AN/APG-68 that is fitted to most current-production F-16s, and can track up to 20 targets simultaneously or up to six with the accuracy normally associated with single target tracking
    Fighters face the Aesa revolution: since 2000, a small number of fighter aircraft have been flying with Active Electronically Scanned Array (Aesa) radars. To date, these have all been American, but design teams around the world are working to develop

    d) Type of active radar array=Fixed plate AESA array

    The antenna of the Super Viper AESA is a fixed plate that does not move. Gone are the stability limits of the actuators driving the mechanical antennas in other fighters.

    Defunct Humanity: AESA radars for fighters. Brief review.

    COMPARISION TO RBE 2 AESA radar
    So APG 80 has slightly higher detection range than RBE 2 aesa radar by around 10% .But regarding maximum no of aerial target
    & maximum no of aerial targets engaged it is inferior to RBE 2 aesa radar

    But Dassault in order to meet the UAE requirement, the power output will be increased from 9.6 kW to 14 kW by changing the cooling pomp. This should provide an additional 10% range bonus.

    Indian perspective for all American AESA radar


    Unlike the french RBE 2 aesa radar which are offering Full ToT with source codes

    There would have been limited Transfer of Technology on the radar, up to the level approved by the US Government. However, Raytheon stated that the level of ToT offered would be compliant with the RFP requirements

    The technology transfer, though likely to be limited, would meet the requirements of the IAF. Our proposal will be compliant with the request for proposal (RFP) issued by the IAF for the 126 combat aircraft," he said.

    4)Gripen (IN) Raven ES-05 radar
    [​IMG]

    The Gripen had not demonstrated Raven ES-05 radar prototype at that time they had stated it would be installed in future .
    Looking at specifications & configurations following info we have found in open sources


    a)No of T/R modules =1000

    b)DETECTION RANGE Against fighter size target (3m2) = >150km (estimated)
    a thousand T/R modules would generate atleast a detection range of 150km or even higher than that but not less than that for sure

    there are no info /claims about it's detection range at the web one can only speculate but surely 150km+ greater than meteor's bvraam operatioonal range as it is it's primary BVRAAM in future







    maximum no aerial target it can track ???
    maximum no aerial target engaged simulataneoulsy ???

    as no specification is available for ES-05


    c)Angular coverage( Field of regard) = 200 degrees ie ±100º
    source
    Selex to supply Raven AESA radar for Saab Gripen NG fighters - Airforce Technology

    d)Type of active radar array= Swashed plate


    advantage of swashed plate array of RAVEN ES-05 radar

    In long-range air-to-air combat, the highest FoV means that a Gripen can maneuver at an angle in relation to the viewed axis of the target (off-boresight angle) greater than what is possible with an AESA radar with fixed TRMs matrix after launching a BVR missile and still be able to send updated information to the missile. In turn, a potential enemy will be limited to deviating up to 60º of the viewed angle after launching the BVR missile. Therefore, it will still be displacing towards a missile launched by Gripen while this, in turn, will be flying perpendicularly or even away from the enemy missile. Simulations made showed that this capacity should not be underestimated and it will have a devastating effect in the engagement result of the BVR.

    ignoring the swash plate scenario The Gripen E 1000 T/R modules Raven ES-05 Aesa radar would be slightly more or less equal to RBE 2 1000 T/R module aesa radar in performance in detection range basically but not more than that differnce one can expect from it. Until and unless they field GaN T/R modules in future which Sweedish are also planning like French then only
    can they boast of overwhemingly superior Es-05 radar compare to RBe2 aesa radar But at the moment they are plans only for EW suite not AESA radar they are using GaAS T/R modules for ES-05 radar basically.

    But unlike the french they dont have plans of conformal radar arrays in future



    Indian perpesctive
    BTW They havenot demonstrated this AESA radar protype in MMRCA evaluations at all leading to it's cancellation. IAF sources reveal that Gripen failed to provide proof that their AESA radar development was on track and that they could integrate it on a fighter. In contrast, Dassault had fitted two prototype AESA radars on Rafale fighters, proving they were close to completion. Eurofighter, too, test-flew a prototype AESA radar for the IAF evaluation team, convincing them it would be ready by 2014-15.

    5)Eurofighter Typhoon's CAPTOR-E aesa radar

    [​IMG]
    Typhoon consortium group had demonstrated a prototype model of Captor-E/ CAESAR model during the MMRCA evaluations .It was
    touted the 2nd best AESA radar after F22's APG-77 radar thanks to it' enormous T/R module count & aperture size compare to all rivals at that time


    a)No of T/R modules =T/R modules=1400-1500 (estimated)
    The Captor-E will contain about 1,500 transmit-receive modules, and Morrison said the Typhoon’s relatively large nose means it could hold a bigger array than the equivalent radar built by Thales for the Rafale, France’s twin-engine fighter.
    First Typhoon Flight With AESA Could Open Door to Exports | Defense News | defensenews.com


    b)DETECTION RANGE Against fighter size target (3m2) = 240/250km or even higher (ESTIMATED FIGURE)

    Detection range for CAPTOR -M not CAPTOR E

    In 1997 Marconi indicated CAPTOR had detected fighter sized aircraft at ranges of well over 160km and larger aircraft at double that. More recent information indicates the systems range accuracy is within 10 metres while it can obtain a target angle to within 1 miliradian. The system is capable of tracking 20 air targets simultaneously, automatically identifying and prioritising them.
    Eurofighter Technology and Performance : Sensors

    some sources say 180km for a fighter size target
    http://eurofighter.airpower.at/sensorik-captor.html

    So detection range for Captor E AESA version estimated should be higher than Captor M for a fighter size target
    For RCS 3.0 m2 class target should be : 240-250 (minimum value it can also be higher than this value ) but on PEN & PAPER at the moment .Only after proper evaluations we can
    confirm that IF similiar scenario happens like we are seeing with APG 79 Aesa radar then this claim cannot be confirmed

    Other specifications like

    maximum no aerial target it can track ???

    maximum no aerial target engaged simulataneoulsy ???

    cannot be confirmed at the moment due to lack of sources




    c)Angular coverage = 200 degree +

    In addition, the Captor-E will also be mechanically gimballed so that it can be slewed within the nose of the Typhoon, increasing the coverage of the radar from around 90° to 120°
    https://www.rusi.org/images/library/LI53C54BEA6A077.jpg

    d) Type of active radar array =Swashed plate ACTIVE RADAR ARRAYS

    Comparison between FIXED PLATE & SWASHED PLATE ACTIVE RADAR ARRAYS

    The Captor-E will sit on a moving plate, or “repositioner,” giving it a 100-degree field of regard, as distinct from US AESA radars, which sit on a fixed plate. The advantage of a fixed plate, say US makers, is minimal maintenance.


    With a fixed plate, Thales says the radar’s front end needs maintenance once every 10 years.

    But Morrison said the movement of the repositioner required by the Captor-E does not prompt a constant need for maintenance.
    “It is a gentle, rhythmical movement compared to mechanically scanned radars, and the need for maintenance is not great,” he said. “US aircraft fitted with AESA like the F-16 have a smaller nose, and would not be able to fit a repositioner in any case.

    Comparision to RBE 2 AESA radar

    Ignoring the swash plate advantage of CAPTOR -E aesa radar over RBE 2 aesa radar.

    Captor-E on pen & paper is definitely superior to RBE 2 aesa radar in terms of performance & Capabilty thanks to it's increased T/R module count & big aperature size . But it can only be confirmed after proper evaluations & testing if similiar scenario happens like APG 79 aesa radar then !!!

    But unlike the french they havent disclosed anything about GaN T/R modules nor conformal arrays in future at the moment.
    May be perhaps in future we can know about that part


    Indian perspective

    From combat aircraft monthly jan 2013 magazine an article was posted by award winning legendary defence journalist Jon lake
    Eurofighter typhoon what lies ahead?

    In his article he claims

    ....Combat Aircraft understands that Eurofighter GmbH has resolved this impasse and that there is now an AESA radar ‘road map’, with an initial FSD 'Radar 1’ to meet export requirements in 2015, providing a credible export-standard AESA, followed by a ‘Radar 2 to meet core four-nation requirements around 2017, and eventually a derived 'Radar 3' (almost certainly with a new antenna array) to fulfil the UK’s more ambitious needs......

    .....In ‘Radar 1’ form, the E-Scan Captor should offer equivalent performance to the mechanically scanned version, but with all of the traditional advantages of AESAin terms of reliability and multi-mode flexibility as well as enhanced electronic counter-count enneasu res (ECCM).

    In 'Radar 2’ guise the new radar will offer increased detection and tracking ranges bv comparison with the standard Captor-M radar......

    So basically radar 1 which is for exports wouldnot have any increased detection & tracking range than captor M .That means india gonna have to funds it's own radar requirements with the partner states .That would be too sketchy
    & uncertain for india .It would be cumbersome for india to regulate with each Eurofighter partner states to develop & also would be dependent on each individual partner states level of ToT permissible to their own country's export standards











    CONCLUSION

    so after having a nit pick reviews of all aesa radars available during MMRCA evaluations ,It is becoming really clear that
    RBE 2 AESA radar was indeed the safest bet for IAF during MMRCA evaluations




    REASONS

    1) 1st non US & completely french Content operational ready AESA radar at that time of winner of MMRCA evaluations as it was going to be inducted in 2012 .

    2) Did met IAF's requirement of AESA radar detection range of atleast 130km or more just looking at recent trials in mont de marsan air base french airforce indeed claim of more than 50 % increase in range compare to RBE PESA radar & It' detection
    range & specifications is not that bad as claimed by certain self proclaimed defence experts & arm chair generals in india
    as compare to those aesa radars available at that time



    Only E captor radar block 2 variants for partner states & block 3 for Britain may be overwhelmingly superior to RBE 2 aesa radar.That too is in pen & paper at the moment we got to wait in future to confirm that after proper evaluations & testing


    3) Promising future upgrades of RBE 2 aesa radar during MLU program of rafale if india opts for it during 2023+ time period
    thanks to it's conformal radar arrays + GaN tech T/R module leading to increased angular coverage & detection range.
    It would be able to keep up with new level of future threats

    4) (MOST IMPORTANT) Complete TOT of RBE 2 AESA radar with source code unlike other competitors


    Critically for India, the transfer-of-technology (T-o-T) would include that of a state-of-the-art Active Electronically Scanned Array (AESA) radar that would provide Rafale the ability to also function as a close battlefield support airborne warning and control system (AWACS), apart from its designed function as a fighter. The AESAradar T-o-T would also include transfer of software source code, according to Chabriol.

    This is a matter of great concern for India, or any country, that seeks T-o-T of sensitive equipment. Lack of access to the source code would not allow a country to re-programme a radar or any sensitive equipment should it so wish.

    Defence analysts point out that this could seriously compromise India's national security as the IAF would not be able to re-programme the radar should it wish to at a later stage.

    Two other competing fighters Boeing's F/A-18 Super Hornet and the European conglomerate Eurofighter's Typhoon are also being made available with AESA radars though with the provision that transfer of technology for this equipment would be dependent on the decision of their respective governments.

    Earlier statements from manufacturers of AESA radars has been categorical about the fact that transfer of source code is not on the cards. Since source code enables programming of the radar, what this implies is that the IAF would have to specify mission parameters to foreign manufacturers to enable configuration of their radar, seriously compromising security in the process.

    PLEASE NOTE-

    1) I tried my level best to give accurate values of radars as available in the net though mistakes can also happen

    2) I intentionally not included the SWISS EVALUATION REPORT as at that time some planes didnt have aesa radar in those evaluations. So no point of including them here

    3) Kindly for god's sake ignore the grammar & Spelling mistakes in this article

    what is the significance of this article? Right now the situation is such that each contender will be able to give India what it wants.
    It is buyers market and we should behave like a buyer in buyers market where we demand things, for some reason, the Indian attitude (when UPA) was in power was submissive, making it buyers market all over the world but for us it was sellers market, so the Russians were able to demand and we were complying with their demands. The Russians have not given us ToT as promised for the main gun of T-90, and strangely we are not demanding it. We should not be able to tell the russians that since you do not comply with ToT we shall produce T-90 as we want without paying the licence fee. and each tank that we produce now, the licence fee should not be paid. And only after they transfer the tech, and since then we can pay for the licence, and not for the tanks that we made during this time.

    Yours article is excellent but with just 10-12 kw peak power rbe2aa aesa will not be very good wrt to jamming much powerful radars like n036 of pakfa,,,not that we will face pakfa eventually.
