    didnt you even read the interview with french defense ?

    What the Emirians are calling for is much more complex. They want, in addition to the AESA, to have new functionalities on their Rafale, such as GMTT / GMTI detection and tracking of moving ground target, interlacing between air/air and air/ground modes, etc
    (do you know what this means ?)

    the key Emirian demand is about the range of the RBE2. And, with the same antenna diameter, the only way to achieve the 10% range increase (compared with the Basic AESA F3 “roadmap”) that wish to obtain the Emirians, is a big boost to the power of the radar.
    But more power to the RBE2, could it be a risk to generate serious electromagnetic interference (EMI) with the SPECTRA receptors ?
    There is indeed a very real EMI risk to treat. This is the case whenever we want to change aircraft emission systems. There are solutions, obviously, but this will require to reexamine SPECTRA. But the biggest problem we have identified is about electric generation, which could be insufficient. To increase the maximum range of a few nautical miles, we would have to deeply review the electrical generation system of the aircraft.
    In short, to conceive what it could be a Rafale-9, that is to say a new aircraft moving away from the similarity you want with french Rafale.
    The Emirati experts participating in negotiations are well aware of the problem. But they are also used to have very high quality weapons systems. They want to avoid any regression with the Rafale, at least on the radar range, compared to the F-16 Block 60,
    (he seems to acknowledge there are somethings rafale cant match)

    Beyond the radar, they are showing fairly strong requirements into SPECTRA development with, for example, the expansion of some frequency bands, an increased sensitivity, adding functionalities; in short, they want we push up the current technologies. [as said previously by uae, to bring it up to the current standards]

    rbe2 and spectra needs some very serious money spent on it

    gee that was easy, so you have no points other than this assumption of where i got the term from ?

    function rather than the mmic, the rbe2 is pretty basic compared to what the yanks are doing now

    in your dreams, lets see some links to back yourself, i have given dassault fox three links to where the aesa antenns is simply added to the 1995? PESA backend, only recently here
    thales can do a decent radar if given the money, they havent been given the money

    -The RBE2 comparable to the APG79 comes from Thales engineers which are certainly more aware of the situation than you, You are mixing up number of modules and AESA technology. The F16 block 60 may have more modules but that doesn’t mean its AESA technology is more advanced.

    -Gripen radar will suffer from the same size constraint and will have to cope with less electricity production. You are ignoring the result of the FAB evaluation which was much more telling and the Indian criticism which may not be a coincidence. (Un)Surprisingly the RBE2 AESA was not criticized. Its tests by the swiss was also a success. Just that you are brainwashed to bash anything french. Which is your only hobby on this forum. You are not even a true supporter of an aircraft.

    -Radar modes is a matter of operational requirements. GMTT/GMTI is something quite specific that not all airforces are asking for. This is a matter of software development and has nothing to do with the technology and the performance of the radar.

    From what I understand the current RBE2 AESA is marginally shorter in range than the APG80 but with a smaller radar. So you cannot conclude anything on the technology which is even more advanced according to Thales as it compares it to the APG79.

    A big difference with you is that I am able to change my opinion according to new sources because I am genuinely interested in what approaches the most to reality. You are just here to bash the rafale and french.

    ok, put up the link where the thales tech said its comparable to the apg-79 and why he thinks this, then we will take it from there
    the french are just lucky that mainly UAE wants is similar range to the apg-80, there are modes requested that simply RBE2 hasnt got and god forbid if they wanted it to be as good as the apg-80

    http://www.es.northropgrumman.com/solutions/f16aesaradar/assets/aesawhitepaper.pdf
    the f-16 Northrop-Grumman apg-80 is 4th gen, RBE2 is comparable to Northrop-Grumman 1985 1st gen
    it has nothing in tech to raytheon apg-79, as its a different tech tree entirely

    as i see it….a lot higher power than the ambient ems is easier to detect than a radar that works in the hash, so i wouldnt get too excited about max output, the way it transmit and especially receive sensitivity is more important,
    the advantage of more tr modules is that you can use less power for the same result, or you can focus in a narrow beam for a long range
    like engines, radar’s arent run at max either

    PS
    i know thales is well able to design decent radar, i dont see the RBE2 being one of them at this stage, they need a bucket of money that isnt being provided to do that
    so until that happens i see it as lacking even to the gripen on tech grounds
    as to it being comparable to a apg-79,,,,,,Please !!!! enough of this nonsense, it isnt

    PPS @ LOKE
    do a google and get the modes and what the gripen radar can do, from what i have read its impressive and it will help you to show that compaired to the rbe2, it is far from lacking
    i have got involved in posting stuff about it, but it falls on deaf ears,
    like arthuro, even when he is shown to be wrong, you too may copy paste it on every second page

    they would probably have a white paper stating their reasons, but i havent seen it mentioned

    that link said they’re spending 60b over 10 yrs, so they are serious, what ever the plan

    here is the WSJ article with more detail

    it seems its all go,
    A proposed U.S. arms sale to Saudi Arabia would include about
    *70 UH-60 Black Hawk attack helicopters, shown in Iraq in November 2009. The deal would also include up to
    *60 Longbow Apache attack helicopters.

    The UAE don’t have AWACS. That the reason why they ask for the maximum radar range possible.

    kovy, you read fremch, perhaps you could open the pictures at the bottom of the post at mp.net
    if you could do a full translation of that paragraph, perhaps it will make more sense, my school boy french isnt up to the task

    i wonder if Olybrius has the full interview, it would be worth reading
    Admiral Alain Silvy does indeed state it as it is, the ‘good’ and the ‘needs improvement’

    He is like Rezende. The only difference is what Hammer brought was his opinion like a Brazilian observator when Rezende had some hard datas and facts to provide from the FAB evaluation. Look at the previous thread, Hammer and Rezende know each other and there was respect between them.

    But some will stick to the only part of the story that fit their wishes.

    i was answering your “Some guys are so stressed by the truth that they are ready to hang on anything to keep living in denial.”
    which you again posted similar in you current post
    i’m afraid you’re the one that is grasping and clinging
    as this isnt the case at all, as i dont really care about nordic work with brazilian firms
    i would seek a second source if i was interested in what is being posted, as i found his previous omittance of facts known to himself, disturbing

    does anyone know if they paid their money to eval the f-35 yet ?
