i’m acknowledge i’m a pleb and if you explained this at the beginning instead of the end
we all would have saved some time, i will send thales an email as i still dont understand how the spectra jammer is electronically steered and they might have a diagram of it
i still dont understand how the spectra jammer is electronically steered
Just like the radars… What’s the problem ?
ok, is this a translation thing, aesa is also called active phased ?
http://en.wikipedia.org/wiki/Active_Electronically_Scanned_Array
An Active Electronically Scanned Array (AESA), also known as active phased array radar is a type of phased array radar …
I think this sentence says it all. (nice to see that you read my messages carefully)
LOL no it isnt
This thread is full of reality denial. 😀

What a pity ! The link is dead.
So, we have a system which uses :
the current RBE2 active phased array
On the current RBE-2, the array is not active.
Spectra is the first french military programme to start such a high scale production of AsGa MMIC…

APA and AESA, well they are virtually the same, except for the different meaning :rolleyes:
An Active Electronically Scanned Array (AESA), also known as active phased array radar is a type of phased array radar whose transmitter and receiver functions are composed of numerous small solid-state transmit/receive (T/R) modules.
So… Spectra uses active phased array for the AESA jamming technique. Then ?
we are talking the jammer transmitter system arent we
‘active phased-array’ isnt ‘Active Electronically Steered Array’ is it
excuse the wiki link, but it does provide a broad over view
http://en.wikipedia.org/wiki/Phased_array
Can you tell me how to shift the phases, if not electronically ?
Well, jackjack…
We have PHASED ARRAY transmitters and “AESA jamming” technique all together…
I’m still looking for another Thales brochure which was more explicit, but i think you’re doing your best not to see…
as i said, i think ‘aesa jamming’ refers to an ability to jam aesa and as such doesnt need any aesa equipment and not meant that the rwr/jammer is an “Active Electronically Steered Array”
Strange idea, don’t you think, to tell “ability to jam AESAs on 360° !”

SPECTRA
Loading…The SPECTRA system for the Rafale combat aircraft operates in electromagnetic, laser and infra-red domains. Using sophisticated techniques, such as interferometry for high precision DOA and passive ranging, digital frequency memory for signal coherency and active phased-array transmitters for maximum effectiveness and covertness, the highly advanced multi-sensors and artificial intelligence data fusion capabilities of SPECTRA provide the Rafale aircraft with the best chance to survive in harsh and lethal environments. The Rafale combat aircraft and the SPECTRA system are fully operational onboard the French Navy’s Rafale.
Offering unique high sensitivity detection and multiple threat capability, and operating smart data fusion between multi-spectral sensors, it provides identification, location, jamming and decoying against an extensive range of electromagnetic, infra-red and laser threats.
Additionally, SPECTRA fulfils new functions in a combat aircraft, while significantly participating in the determination of the aircraft’s tactical situation, and providing the crew with operational advantage by performing accurate threat location.
By virtue of its fully passive situational awareness capability, SPECTRA is a major contributor to the low observability concept of Rafale.
“active phased-array transmitters” Do you agree ?
There is this video too
http://www.kakimediadesign.com/2009/thales-onboard-the-rafale/
(watch it in full screen and HD)

360° solid state RF AESA Jamming
http://www.thalesonline.com/Pages/PressRelease.aspx?id=10850
The system’s cutting-edge defensive measures are based on combinations of omni-directional AESA jamming, multi-band decoying and evasive manoeuvres, as well as on state-of-the-art technologies such as Digital Radio Frequency Memory (DRFM) signal processing.
Defensive measures based on AESA jamming…. This should need AESA…. somewhere.
Still looking for other sources.
JackJacko, i’m searching on my hard drives, i’ll tell you ASAP.
are you sure you gave me the right link, i cant see aesa mentioned on the page. only the future aesa radar
i dont think dassault has claimed that they are asea based rwr or transmit
Look at this :
Full integration of the AESA RBE2 positions the Rafale as the only combat aircraft of its category equipped with active arrays for both its radar and electronic warfare suite. This outstanding system that allows a 360-degree smart antenna array coverage, is a real technological breakthrough on-board the aircraft.

http://defense-update.com/features/2008/november/rbe2aesa_rafale_081108.html
There is also a Thales brochure where it’s said that Spectra uses AESA but i can’t find the link.
the 1 deg receive and transmit ?
Search the article “killer angels” by Bill Sweetman. I’ve checked Fox Three (issue 4) but it’s not in.
its a shame no one has asked him or thales or dassault to clarify what he said and meant by invissible, was it deception, different range, different aircraft, showing multiple aircraft, etc ?
We have no answer.
Even AC is just a journalist’s suggestion. So, imho, we simply don’t know, and aren’t supposed to know :D.
There are some very specific techniques to obtain the signature of a real LO [low-observable] aircraft.
We don’t know what he was referring to.
the other thing i have been wondering, and as i have said, i’m a pleb
“Dassault has stated that the EW transmit antennas can produce a pencil beam compatible with the accuracy of the receiver system (1 deg), concentrating power on the threat while minimizing the chances of detection”
Information found in Fox Three for the first time, but also published in several publications.
i fully accept directional rwr and have seen ‘sector’ but not the 1 deg
as for the jammer transmitting on 1 deg, i would like to know how its done as i havent heard of this before
Some of the arrays of Spectra are AESA (this is why Thales claimed that Rafale was already equiped with a 360 degrees AESA set).
You may want to look at this : http://rafale.freeforums.org/post102.html#p102
By the way, i’m not sure Dassault/Thales are the only one to claim they achieved the “under one degree” accuracy for ESM/ECM.
It’s not that i’ve no argument, but i don’t want to be labelled as an Active cancellation moron.
And I don’t really care about this feature. Arthuro consider AC as a rumor, and so he thought about the ISAR NCTR. That’s all.
