arthuro, while you’re on line, do you have time to answer my post to you in our conversation #80, so we can continue

it might be a bit too advanced for me, i’m still having trouble putting on the crotchless batman suit, i sometimes get it on backward, leaving myself vulnerable to various strange practices that i still find disturbing

it was nicely said djcross not many include the scattering aspect changes from various parts of the frame

its just a shame for bluewings fantasy of a future active cancelling radar system is,
its not the way the tech is moving, offboard active & passive and onboard passive coherent location. in conjunction with various VLO systems
i know the tech set is currently being developed for subs too, eg ‘acoustic daylight’
as well as the almost unsurmountable problems of x band AC, its hard to AC a signal from an aircraft, when it isnt transmitted in the first place

the uk is putting the asraam and the cruise missile on the f-35,
the meteor, iris-t, the Norwegian naval anti ship missile is going on too
there are probably others
uk wont get the core code, frankly even as an aussie partner i dont want uk or oz to get it either, the more countries that have it the less secure it is

@ Erkokite
truth is i didnt know what a bragg cell was 12 mths ago, till bw was slapped about it, after reading something he liked and decided that the rafale had to have it
the consensus seems to be that rafale uses one of the analog types, most say the Superheterodyne which isnt instantaneous like the bragg and 2 other analog instant
i know there are a lot eu nations working in several partnerships on GaN and one eu manufacturer of it, i think
it will be COTS GaN as there are limited manufactures of it world wide and lots of development companies going to use it

well there is a big problem if it turns out that way, i read it as they wanted more work share or wanted usa to kick in more money, but if italy cant do it some nation in euro will be nominated for regional hub, there is also going to be one in the asia pacific
there will be a profit and employment for whoever does it and every nation likes that idea

well on past performance, it wouldnt be amiss of me to question what you say re the fa-18 jamming ability, at one stage you said it didnt even have a jammer 😀

there is nothing wrong with the rafale that money wont fix, there’s the problem that has plagued it since day 1

if only you had a link to your ‘thinking’ rafale uses bragg cells, it seems you are the only person in the world that thinks so, going by google search

there are more than france and germany in the euro GaN research group
by the way Raytheon is already there

Raytheon’s Gallium Nitride Establishes Radar Technology Standard
Aug. 31, 2009 /PRNewswire/ — Raytheon Company’s (NYSE: RTN) innovative gallium nitride (GaN) chips have achieved 1,000 hours of reliable operation, positioning this technology as the standard for next generation radar capability.

GaN technology provides increased reliability and efficiency, resulting in lower prime power consumption and relaxed cooling requirements. Thus, GaN T/R modules provide significantly higher long-pulse radio frequency (RF) power than that of standard gallium arsenide (GaAs) T/R modules.

Most notably, Raytheon engineers have now successfully demonstrated the reliable operation of a GaN power amplifier microwave monolithic integrated circuit (MMIC) operating for more than 1,000 hours with no measurable performance degradation.

they already have a radar system in development, 2008 update

AESLA’s overall approach involves leveraging GaN’s performance, sharing the amplifier across a group of elements, and adding a low-cost phase shifter at a higher level
Whether internally funded, or funded by the government, it may be that a higher priority effort would be able to deliver faster answers regarding AESLA’s viability, and bring its capabilities into service at an earlier date that the current implied schedule of 2014+

its fair to say the fa-18 will have GaN well before the rafale does
although it may well be from Northrop Grumman

Northrop Grumman set a new world record for transistor speed with an ultra-fast device to provide much higher frequency and bandwidth capabilities for future military communications, radar and intelligence applications.

The NEXT program is designed to enable revolutionary advances in nitride electronic devices and integrated circuits resulting in their ability to operate at very high frequencies while maintaining extremely favorable voltage breakdown characteristics. DARPA is looking for ways to overcome the limitations of nitride-based electronics technologies, such as gallium nitride (GaN). “GaN: DARPA’s 3-Pronged R&D Strategy” has more on DARPA’s GaN research efforts.
