    Lukos engineer… When are you going to understand that this is the RAFALE thread and that it is completely derailed from it’s original topic since XX pages because of your (and friends) obsession to be right ? STOP POSTING HERE. And MODOS , please lock this thread.

    Agreed!

    I plead guilty.

    But again, having a degree (I am not questioning lukos’ qualifications) does not prevent you to be biased (no more than a few days ago I had a short discussion with an aerodynamics student denying some Rafale performance. He solely based his arguments on F-16 E-M charts, I’m not gonna explain why it is irrelevant and bad faithful), and reading many of lukos’ posts kinda made me skeptical on his assumptions.

    Interested in explanations 😉

    Still not answered my question. Do YOU or others here have any experience in air strikes, I mean REAL one like being staff planning missions, or being aircrew… ? Or maybe being aero engineer ?…

    I have for CAS, but from the ground tbh

    Depends on the cause.

    praobably a hydraylics leak.

    the pattern are random thus record them wouldn’t help ( i dont think it hard to program a AESA to choose randomly a frequency from 8.001 Ghz to 11.999 Ghz every time it transmitting)
    Patterns are also random, and let be real, even if it isn’t perfectly random, and it have a certain pattern, radar still have the advantage of knowing exactly what coding, frequency, waveforms that it use , while the RWR will have to solve problem to figure out. Which is why i said deceptive jamming gonna be highly ineffective again AESA radar, and noise jammer should be used in such case. It also the reason why delicated jammer like NGJ, ALQ-99 required very high transmitting power, they are noise jammer

    Did i say the oppposite? But the idea is break kill chain. And a radar must recognize his own signal returns from clutter. To do so he uses headers. These headers can be recorded and used. Exacly like your GPS is recognizing GPS signals (around 20 watts…)
    Nothing is perfect of course, but like saying stealth is useless, saying AESA are jamming prone is a bit excessive.

    a data based are used, because otherwise the jammer will overload itself trying to retransmitted everything it received from background noise
    it doesn’t matter how fast you can converting a analogue signal to digital one, you still have to analyse it, there is no way around it, think about it, what is the difference between a deceptive jammer and a noise jammer? , a deceptive jammer try to fool enemy’s radar into bealiving the jamming signal is the reflected signal while still created false information in the jamming signal
    both side will have to deal with multiple wavelength, coding and random scan pattern , PRF but the radar side know exactly what it send out, thus it doesn’t have to waste time trying to separate signal from noise, the tracking of target required range, velocity the first are calculated by taking : speed multiple with time, the second are calculated by looking at the doppler shift

    you are trying to argue that a ECM system which doesn’t know the frequency, scan pattern, PRF rate, waveforms, coding.. etc from the start, can somehow magically analysis, modify, and retransmitted enemy radat signal faster than the reflected signal can come back to the radar source, that is simply nonsense, it like saying it easier for someone to guess the password than for the owner to know his own password

    Agree, but.
    Thats where the notion of repetitive patterns is coming in (remember when i said not 1000 different wavelengths?)
    Patterns can be recorded and compared using massive parallel correlators…

    As stated low level flight doesnt help again air threat , and deceptive jamming wouldn’t work well again AESA that change their frequency a thousands time / sec either , you need a noise jammer for that , NGJ , ALQ-99 required very high power for a reason

    As stated by who? You?
    Just one point for you to to think at : frequency hopping 1000/sec do not mean using using 1000 different frequencies. Same apply to waveforms etc.

    RIP.
    It was first delivery flight of MSN 023. Plane was sensed to go to Turkey, but was tested by a six spanish people crew. 4 of them are dead, one in serious state, another in very serious state.
    Best to families and colleagues.

    It seems that LM copied 360 degree DAS from elisra. I wonder why french didnt implement it together with 3rd DDM-NG it could be good checkbox feature since fanboys like it it must be good

    Because it would mean rewiring the plane and rewriting spectra software.

    well the photo probably taken before the shot, unless you can prove otherwise

    i already copy pasted the discussion i had with the pilot. If any of you is going to PAS 15 btw, he will be there. Oh and btw i work with Defesanet, the news agency he is working for in Brazil. easy find.

    After fisherman’s tale. Report from incident shows picture that says 7.8nm. No missile was fired, therefore no proof of capability took place.

    blah blah blah… The photo was NOT taken during the shot. you would have seen the missiles but nvm no use talking to deaf.

    Depends on the range of the missile and the seeker. Meteor is capable of real world intercepts at well over 100km and has a narrow-beam ARH seeker, so after a minute or more of flight time, that narrow band seeker needs an update and the advantage of the two-way link is to inform the firing aircraft when the ARH seeker has lock allowing them to go fully defensive and evade anything coming back the other way. In the case of ASRAAMs and MICA IRs with wide-angle IIR seekers and real world ranges of 30km head-on, I doubt an update during the few seconds of flight between firing and automatic target acquisition is very useful, especially when the firing aircraft will point the missile towards the target anyway. The CAMM (M/L) on the other hand is based on the same missile, is vertically launched and has a narrow-beam ARH seeker, so knowing where to aim that beam is necessary.

    It’s now ‘over 20nm’ IIRC, so what will it be next year? Over 30nm perhaps? We’re also arguing about the details of a non-shot here, i.e. not a live fire. I could nail a domestic cat to the pylon of a Tucano, detect the approximate position of Mirage on my six, and simulate a launch, and still have demonstrated the same capability as this test did.

    The first time i said way over 10 nm. After checking data could be disseminated on the net i say 20nm

    Internet spell-checker default is the culprit I suspect.

    Pitiful attempt. Want to try to continue in french?

    The range of the MICA VL is 20km, the range of CAMM (L/M) is 25km and that’s only 10% longer than the ASRAAM an is weighed down by a datalink. I could also mention CAMM-ER at this point but I’ll leave that topic. It’s kinematically the best short range AAM on the market..

    vs (MBDA site)

    CAMM for future Air operations
    The same CAMM missile design for Navies and Armies is easily adaptable by MBDA for Air Force use on
    Fast Jets. With MBDA’s experience from ASRAAM and Meteor ensuring world class performance will be
    achieved. MBDA has been working with the MoD on assessing how CAMM technology could be used to
    sustain or enhance the Royal Air Force’s ASRAAM capability in the future

    And…

    The UK Ministry of Defense is funding an MBDA study of future family of
    ‘anti-air’ weapons known as the Common Anti-Air Modular Missile (CAMM). The new weapon will utilize the airframe and some of the components used with the Advanced Short-Range Air-to-Air Missile (ASRAAM) and introduce advanced
    and enhanced capabilities for aircraft currently deploying this short range, heat seeking missile. But CAMM will be aimed at more applications than AAM

    CAMM shares some components and aerodynamics with ASRAAM, but it is IMPROVED. You can’t conclude the range of missiles from their evolutions in another environment. Flawed logic.

    Does it have a bigger RCS. All RCS estimates have been ~0.1m^2, which is at least as good as a Rafale. HMCS benefits not worth the costs? LOL. Much like the Meteor 2-way datalink LOL. Case of higher-hanging fruit I think.

    The F-18E/F will still be supported with upgrades until the F/A-XX, it isn’t due to be replaced by the F-35, which replaces the F-16, F-18A-D and AV-8B.

    Higher g-load without HMCS is no use.

    Armée de l’Air did not buy HMD, But it is available for export. In fact it was a request for MMRCA. Are you sure it is not integrated?
