    Would you have a picture of a Gripen with the said recon pod?
    IIRC one of the other reasons why choosing "wet-film" was because the digital ones are so easy to alter. For instance, if you claim you have photographed a countries WMDs and start a war over that, its important that the evidence can´t be faked so easy. No one wants a country to go to war on false premises.

    In addition they are said to be still superior in terms of resolution and picture quality in comparison to the digital system available on the market.
    At least that was claimed by the German MoD during the discussion about the deployment of Recce Tornado's to Astan.

    The Gripen is one beautiful aircraft.

    Yes, beautiful jet!

    Does anyone know what the current unit cost is?

    I did just see a huge airliner being escorted by a Gripen when it took off from Saabs airport, made a circle over the city and the disappeared in the horizon, perhaps it was som VIP:s or could they have been testing the new NG version? They did fly very low which made it an awesome sight!

    No news this week so maybe just sit back and watch a movie...

    Still from another new Saab movie called "Ambush" which I posted on a while back

    Director Patric Ullaeus and the Revolver Film Company has started to work on yet another film for SAAB's fighter jet GRIPEN.

    Let's hope it's even better than Controlling The Battlefield.

    [SIZE="4"]AESA:s need fast processors[/SIZE]

    [IMG]http://i28.*******.com/ji28vkdotjpg[/IMG]

    Already back in 2001 Ericsson had developed a processing unit around 100-times faster than now operational systems in 2008.

    With all the forum talk about AESA radars these days I pulled out this info on a late 1990s research project by Ericsson Microwave Systems (Now Saab) and Hamstad Uni on a new signal processing system to be used with the ever more demanding AESA sensors.

    Taking in and processing the enourmous amount of data is a key challenge to deliver operational AESA radars with added capabilities. Ericsson who produced the first operational airborn AESA found that there were no processors on the market fast enough for the next generation systems.

    And not even fast enough to be used as nodes in a scaled system so they developed a Application Specific Integrated Circuit (ASIC) on which processor arrays would be placed. The ASICS were then interconnected on a board that would go into a processing box to be used with a AESA sensor.

    What they came up with in 2001 was a ASIC containing 25 GFLOPS of processing power, each board had then 8 ASICS and each box had 5 boards. Totalling over 1 TFLOPS of power.

    Not to be viewed as what will be in Gripen or what's even in the research labs today. It's just a piece of information on research at the turn of the century. [IMG]http://i14.*******.com/4l7a26cdotgif[/IMG]




    Summary
    We have designed a signal processing system that meets the requirements, including tight size and power constraints, from future multichannel fighter radar systems.

    Heh nah nothing major. He has just been basically copying posts from mp.net and posted them elsewhere without a credit. It's rude. But eh, no biggie.

    lol, i will give you credit from now on, i just didnt know if i were allowed to link to another forum.
    otoh its a credit in itself to you that i cite you, i wouldnt post it if i thought it was crap. i didnt pretend it was my own stuff, i said "someone"
    next time i refer to signatory.

    morboute i cited signatory's exellent info/calc. on range on JSF/JAS/EF page 13 in this thread.

    Another thing signatory: i feel that gripens radar range is short compared to Su-27+ :why not rip out the radar receiver in front of gripen, cram in as powerful transmitter as possible, and spread out the receivers on pylons, wingtips, etc ?

    I also wonder if more computing power can negate the advantages of VLO by better analyze the few photons that still will come right back to the plane ?

    Heh I am not angry it's overall good but I am protecting this board and this thread that's the point I want to make... and I also want to make you aware you're going against a couple of rules on that other forum (21 and B) which says you need to supply sources (not forum links) and refrain from posting copyrighted material (which our words are). Remember we're posting on commercial services... we don't make money but the owners need some $$ to operate the sites that we do use. (Traffic=money.) And I want more traffic to come here that's why I don't post over there..

    It was these most recently that looked a bit "fishy"..



    Your other questions on radar is not really something I can guess on.. but I know low signal processing power has been a obstacle not just for the AESA development but also the IRST sensoring as to get usable signals at long distances. In the future we're likely to see the AESA sensorfuse with a IRST to provide a scan and track that is very effective against 'stealthy' targets at a fairly decent distance.. we could probably learn together with Italians and French in this regard. There's also the electro-magnetical field to think about. We'll see what the brains come up with
