    Unless this is bogus it’s from Reuters and other news agencies, or search at wikipedia, or on the Vera system.

    PRAGUE, April 1 – The Czech defence ministry said on Thursday that it was trying to trace dozens of surplus Czech-made “Tamara” anti-aircraft radar systems after a report in Germany claimed some may have fallen into Yugoslav hands.

    The Tamara, a web of electronic cylinders usually carried in heavy trucks, can allegedly detect the U.S. radar-evading “stealth” fighters which have been used in the NATO air campaign against Yugoslavia.

    One U.S. F-117 stealth fighter crashed during a raid last weekend but the pilot was rescued, and it is still not clear whether the aircraft was shot down or crashed in an accident.

    The Czech Republic, part of the former Soviet bloc but a NATO member since last month, has been under close Western scrutiny over arms deals, especially the Tamara system, in the years leading up to joining the alliance.

    Germany’s ZDF television on Wednesday quoted a British security analyst who cited U.S. intelligence sources as saying that a Tamara system which the former Czechoslovakia sold to Russia prior to 1990 had been passed on to Yugoslavia.

    Czech defence ministry spokesman Milan Repka told Reuters on Thursday that tens of Tamaras and the predecessor “Ramona” had been discarded as part of a conventional forces reduction agreement after the end of the Cold War earlier this decade.

    “The ministry is checking on whether any of the discarded (Tamaras and Ramonas) made their way to Yugoslavia,” he said.

    Repka said the ministry was tracing documents on the surplus systems but could not verify if other countries may have re-exported them.

    Tamara’s maker, the privatised but struggling HTT Tesla a.s. located in the eastern Czech town of Pardubice, has been accused on several occasions of trying to sell the Tamara to countries considered antagonistic to NATO.

    But Czech government officials insist that their post-Communist arms export controls have prevented potential enemy armies from obtaining illicit arms and the Tamara.

    A spokesman for the Czech intelligence service BIS told Czech Radio on Thursday that it was unaware of a Tamara being sent to any crisis area or hotspot in the world.

    passive

    Yes it’s a theory because there are no facts that are against or in favor for it…

    see this link by some reputable newspapers discussing this subject and make up your mind for yourself:

    http://www.aeronautics.ru/tamara02.htm#The%20Czech%20Republic%20will%20export%20its%20Tamara%20radar

    But for me it’s not about who or what, but if it’s possible to use a system on a fighter that uses background noise from various emitter sources to get a space image, and being trully passive and not having to use the oponents emitter. I know for a fact that the systems exist. In proper terms it is called;
    passive coherent location or passive covert radar.

    They use a lot of emiiters like;
    Analog television signals
    FM radio signals
    GSM basestations
    Digital audio broadcasting
    Digital video broadcasting

    To get an air picture.

    My question is this, can the system be minituarized to get an passive radar system to be fitted on a jet, or to be used like an E-3 and data linked to the fighters?

    Because especially when you can put the system on the figher as a stand alone system it would be in my opinion be un-jammable.

    I think there was an article about it in this forums magazine a few years ago. Yes it was a theory but is seems feesable to me.

    And the Chines didn’t acually shot it down but had the passive radar equipment integrated in the FRY air defence system.
    And the passive radar was situated in the chinese Ambassy.

    To come back the JDAM bit. I’ve read an article this forum’s magazine that the JDAM was used with E-8 tracking of moving targets!

    Pssive radar

    Before we only talk about the F-22 vs F-XX ‘s radar, my question is more about using background noise from every emitter that’s arround to get a fix on aircraft. Just like the system that was used by the Chinese to shoot down the F-117 in Serbia.

    So, correct me if I’m wrong it’s possible to track, lock and launch a missile in passive mode? (no radar illuminating by A/C)? Or does the missile need guidance (from the A/C radar) untill the last fase where the missile’s radar take over. Or is it also possible to use data link with the missile and not use the radar at all?

    Blurred areas

    Just some, if you use google maps, soem sensitve areas are blurred so can’tsee anything really. I tried to look at some dutch airbases and nothing can be seen there.

    If,If,If

    I find this a very interesting topic, but we have tackle the question one at the time.

    First.
    Yes the S-300/400 are formidable air defence weapons. That can take on every weaponsystem that is in use today. The weapons of the future is a non topic if you ask me because, the S-300/400 will be evolved or replaced by a new system, to counter these new weaponry.

    Secondly, The Raptor as a weapon platform is top of the bill today, and also very expensive. yes it’s hard to shoot down if used in the right way. And that’s what is the real problem today. I have the idea that because the F-22 is such a new A/C we will lose some in the beginning because the new tactics/platform will only work if everything works. ( I mean the whole centric warfare,data links, comms,data management/ threat priotizing ) I’m a little sceptical about that.

    I’ve seen nice pics of migs being moved arround in Divulje (split airfield) I’ve aircarft chelters going in to hillside chelters very interesting how much a?C can be stored there? is it still in use, not so much activity lately….

    Croatian PC-9

    I’ve been in croatia last month and I saw at least one pc-9 flying by daily, from zadar A/B. How is flying the bombardier firefighting planes? Is this the Airforce?

    In my experience with rotary aircraft the newer generation MAWS looks at The UV light spectrum to detect the incoming missiles. Helicopters biggest treaths are manpads and SAM systems. The MAWS sytem deploys Flares automaticly, and combined with breaking manouvres should break the lock of the incoming missles ( I personally don’t believe that it would work with the newer misseles) But the MAWS system gives you the time to break the lock by using the terrain (hills/ trees/etc) And that’s an advantage if you compare with fast jets. Most of the jets don’t have MAWS, only RWR.

    Also you have to take in account that in any modern war, the SAM systems can’t use their radarsystem for a longer period because of the danger being attacked by anti radiation misseles and electronic attack/jamming.

    So I think both systems (airplane/ Misseles) have their downsides and the diffence wich one is going to win who uses his recources (jamming/attacking/terrain/ SEAD support…. VS ….tactics/ radar networking /anti jamming attack in the best way.

    v-22

    I do not entirely agree on that, yes the v-22 costs a lot, and there a lot of problems now, just like the days of the early jet fighter era, but if the figures from the manufactures are right, there are no helicopters that come close if we talk about cruise speed/ effective cargo load/ range. So what I is think we have to think that this is not just a helicopter with better performance but a new kind of asset, that is going to change the air assault concept. 🙂

    What is the purpose of that thing? Spraying the enemy with chemical agents?
