There is none .
One only has to understand how the system is working to know that Bragg Cells are present . In the same way , one only has to understand that the ALR-94 (F-22) is also using them and that the Typhoon and Gripen are not . But it is beyond your understanding 😡

The differences in between the ALR-94 and Spectra are mostly in the receivers sensitivity amps . Both systems have probably the same bands range (with an edge for Spectra in S , Ku and K bands) and both systems can accurately give the exact bearing of the emitter .
Spectra is also said to archive some kind of ranging through interferometry .

The hardware behind Spectra IS the World best .
One knowledgeable person only has to check this link :

and read through the different articles to make his/her mind 😎
Now , you know .

jackjack , not being cocky but you should just listen and read . Then , think , make your own mind up and come back here 😉
Please , spare us your non-sense and learn a bit .

Cheers .

so in other words you are telling fibs and its just a guess b/c it sounds good

The F-35A/B/C will also require E/A-18G support in contested / defended territory. The Next Generation Jammer is in early development and will initially be integrated into Growlers, and later deployed on a F-35 airframe – if EA/EW workloads can be simplified enough for a single-crewed aircraft, and they can figure out where to stuff all the associated electronics.

thats true for some missions i guess, although the f-35 jamming is suppose to be very nice,
aussies have no plan to keep their fa-18f/ea-18g after 2025, so we seem confident in the f-35 jammer capability
it seems some of the ea-18g’s are going to the airforce, and the f-15 is having stand in jamming to work with the f-22 for now

Thanks for the info, but I wouldn’t take the musings of a (admittedly very, very biased and mostly wrong) strategypage forum post as gospel. 😀

Anyways, what he says does make sense about the low bandwidth MMIC’s- and I see why one might think they are from the USA, as the USA has (or had) a lead over Europe in the MMIC industry at the time of SPECTRA’s development, and likely the MMIC parts available at the time of SPECTRA’s development were probably very crude, especially if they were export quality. But MMIC’s are basically a low-level part and have nothing to do with the actual implementation (i.e. SPECTRA). For example, an American company might import parts made in Japan to make a radio, but how the parts are put together and used is up to the American engineers.

So while Thales could use (or could have used) American manufactured MMIC’s to implement SPECTRA, they actually did the design and programming of the system and sourced an American supplier for the parts they needed for the design. Now, of course, the parts they sourced are completely design-agnostic- an MMIC doesn’t care how it is used. They did this for an experimental AESA radar in the early 2000’s, using American made MMIC components on a modified RBE-2 radar. It would not surprise me if they did this with SPECTRA.

There is now a reliable and high quality European MMIC manufacturer (actually there is probably more than one now) in the form of UMS, so now Thales can source European components should they wish it- I know they are using UMS parts for the RBE-2AA radar. SPECTRA will likely use European components and receive bandwidth upgrades if it hasn’t already. I have heard that SPECTRA covers something like 2-20 GHz, so perhaps this has already happened.

I have heard that the highest modes available on SPECTRA are very much a state secret and pilots are not even allowed to engage them outside of france. 😮 So I think it goes beyond the threat library, though that of course is secret too (like Australia’s, the UK’s, the US’s, etc…)

i dont know where they sourced components, only that it was thales usa that designed and made that part of spectra
as to secret modes, when a plane is offered for sale the evaluation see everything, except library and such, unless you are saying rafale has degraded spectra/jamming for export with some tech removed ?

Erkokite its not fanboy to say the rafale has a jammer, its bw fanboy who say its new tech bragg

Stop ! 😡

I think that few posters need to learn a bit more before they keep posting 😡
As I see it , many believe that a top notch RWR only “listen” to few frequencies at once , simultaneously .

That ‘s wrong😡
The problem is , as long as they don ‘t admit the fact , any discussion will go pear shape and in the twilight zone because the corner stone doesn ‘t exist .

Do I have your attention , Gents ?

An advanced RWR based on Bragg Cells is like a mirror . Whatever light waves you are directing at it , it is reflecting . I use optical light instead of radio waves to make it simpler , but it works the same .
Whatever hit the “mirror surface” (the RWR receivers) is acknowledged and can be reflected as it is . As I said before , that would not be of any use .

An advanced RWR is listening on bands L , S , C , X , Ku and K .
Obviously , many things are done through software like filtering and band survey and this is mostly done BEFORE the mission because a good Airforce knows what kind of RF threats they will face .
If it is mostly adverse fighters with some ground military radars , the bands L , S , X will be high priorities and the ECM system will use the needed databank , a bit like a Chess program is using one type of opening library against one player .

If the threats are mostly SAMs , the bands L , S , Ku , and K will get the priorities . And so on … 😎

One also have to understand that duplicating a radio wave while amplifying it to just over the real “Echo” is done in real time by a jammer using Bragg Cells and if it uses a fully digital back-end , active cancellation becomes possible (Spectra around 2015-16) .
As some said , the jammer do not need to understand if the signal is coded , compressed or both . It only has to duplicate it and add some false data on the fly to archive a fool lock from the adverse radar where the range , bearing , ping numbers and azimuth will be wrong .
It can also attack the adverse radar through side-lobes jamming and in doing so , totally *******-up the overall radar picture and putting “snow” on the adverse HUDs .
The ICMS MkII onboard the M2000-5F is said to do marvels in this regard 😎

One also have to understand that a radar is only asking for one thing : getting as much good multiple returns as it can get . Then , the radar is sorting out all the returns through filtering , keeping the best ones to build its picture .
This is how it works but this is also where the adverse jammer is fooling the radar 😎
The best returns will be the ones the jammer is sending back :diablo:
This is how ECMs work .

Now , better the RWR is , better the advantage in BVR is (for early detection) and better the jammer is , better the survival factor is .
This is where the Rafale can beat the F-22 Raptor .
The F-22 doesn ‘t have any jammer and only counts on its radar to direct Amraams . A good RWR will get the APG-77 “pings” before the F-22 gets a lock , from there on , the game is not anymore in the F-22 driver ‘s hands .

The Rafale ~or another well equipped fighter~ will simply stay outside the APG-77 range (3 to 9 O ‘clock) , manoeuver to get in a favorable position and use its passive systems (IRST , TV , IR seekers or even LRF if needed) to fire with a good pk .

The real problem is not to be able to jam every radars around , but to detect them and turn around them to get in position .
This is the USAF stance with the ALR-94 onboard the F-22 🙂

So please , don ‘t tell me that the French approach is wrong because you would dismiss the F-22 ‘s tactics right away :diablo:

The problem is that the Rafale has a top notch active phased array jammer while the F-22 has nothing .

Cheers .

thats twice you posted about bragg cells on this thread
you do realise rafale doesnt have this tech or are you just mixing up your dreams and reality again

like the fa-18, f-35 the f-22 uses the radar antenna for jamming, although they dont have a separate transmitting jammer like the fa-18
the us use offboard jamming for the f-22 to keep emissions low

come on guys, spain will order f-35b or do you think they will sell their carriers that are only suited to them

lets not get too excited about pre-election posturing and a vote that doesnt count in the netherlands

italy is buying more f-35’s than phoons
131, 69 f-35a and 62 f-35b [i looked up the numbers]
why buy 69 a’s if they think their 96 phoons can do it, italy’s phoons have a 4sale sign on them too
