    another polite, correct post, are you going to make a habit of this 😀
    does a 70k tail wind count :diablo:
    i was using the numbers posted in this thread
    there are a few missiles that are trying to improve the end game, but meteor seems to be leading
    it will be interesting to see if we choose the meteor
    lets not start with NEZ, this is hard enough

    are you able to explain to us why the mica ir cant on-board passively engage at that range

    are you confusing passive and active ?

    we use the asraam wvr/just bvr range, with similar functions as the mica ir

    i agree with you and in my post above yours i said about radar and link 16 by off-board data could do it too

    it needs it hand held ? i wonder why it doesnt need a wingman then

    The OSF has a range of around 45 km or something like that. SPECTRA has a significantly longer range, as well as sophisticated emitter identification/locating/tracking modes, I think. If an object is detected by SPECTRA, OSF can be cued to get an image of the target. Between SPECTRA and OSF reasonably accurate data for both azimuth and elevation as well as target identification (via SPECTRA’s threat library) can be found. From these, range can be found by means of either the laser range finder or entirely passively via creative use of nonlinear kalman filters and special maneuvering patterns. Or if there is a datalink present, one doesn’t even need to use special maneuvers. Speed can likely be found via other tricks. From these a firing solution can be obtained. An IR Mica can be fired off based on the given firing solution and then track passively via IR on its own once it is in range (the initial firing solution from the Rafale’s sensors probably handles this). Additionally the missile may be able to be guided via the Rafale’s passive sensors and one-way datalink, but I am not sure about this.

    I’m guessing this is how it works. I’m sure a lot of info on the Rafale’s sensors is classified. I know the EF uses the nonlinear kalman filter + maneuvering/datalink trick to get passive ranging info and I think it is known in the industry as a whole, though it is a bit of an “art”. I’m sure Thales has the expertise to do it, but I’m just guessing in the case of the Rafale as to the exact method.

    Either way it is entirely possible to passively detect/track and fire on a target well outside of BVR and this is a capability possessed by the Rafale, Eurofighter, and F-22, and perhaps some other aircraft as well.

    i think the tv camera osf has a much longer range, the laser designator is the limiting factor
    i think the radar would provide the targeting bvr info to bring it in range for the ir to take over
    i found it easier to split the spectra/osf into its different functions to try to get an understanding of how it works

    link 16 by off-board data could do it too

    i couldnt find a 50-60k ir passive shot, can you point it out for me
    you dont think they mean radar guided loal, do you

    the ir has had loal for a long time afaik
    not passivly it doesnt have the same range and lets hope the battle space isnt too cluttered with friendlies

    i take it you added (namely IR)
    do you really need me to explain those 2 quotes and how radar would be used
    your claim is 50-60k passive ir and i’m still waiting for you and arthur to show me how

    Sounds like I have a step up on you then eh? :rolleyes: How about you simply point out where I’m wrong? I’m more than happy to be corrected provided you do it with facts and not emotional generalities.

    as above, they made us the lead nation because we dont know what we are doing
    here is another read

    the mica rf does have a range of 50-60k
    passive mica ir doesnt by a long way

    how does the osf provide passive bvr accurate targeting data and you can scratch the ir from the osf, even the fr say its obsolete

    yes thales has 2 hms, we have brought one of them, what has that got to do with showing it being tested/fitted on a rafale

    Much as the L band on the PAK FA is at this point somewhat conjecture, isn’t the “F35 will have a great, in fact better than everything else, avionics suite” also a little bit of a finger crossing and praying strategy? 😉

    i dont know about better but the f-35 has 10 multi-function antenna to f-22 30 odd single use

    And you know that how?

    he probably read that L band doesnt provide accurate targeting data

    i’ll wait till he tells me how this is achieved in the first place before allowing for other factors

    gee sferrin,
    you ‘almost’ sound like you know what you are talking about
