    We here at RMF always knew this , anyways another confirmation

    New U.S. Stealth Jet Can’t Hide From Russian Radar

    The F-35 Joint Strike Fighter—the jet that the Pentagon is counting on to be the stealthy future of its tactical aircraft—is having all sorts of shortcomings. But the most serious may be that the JSF is not, in fact, stealthy in the eyes of a growing number of Russian and Chinese radars. Nor is it particularly good at jamming enemy radar. Which means the Defense Department is committing hundreds of billions of dollars to a fighter that will need the help of specialized jamming aircraft that protect non-stealthy—“radar-shiny,” as some insiders call them—aircraft today.

    These problems are not secret at all. The F-35 is susceptible to detection by radars operating in the VHF bands of the spectrum. The fighter’s jamming is mostly confined to the X-band, in the sector covered by its APG-81 radar. These are not criticisms of the program but the result of choices by the customer, the Pentagon.

    To suggest that the F-35 is VHF-stealthy is like arguing that the sky is not blue—literally, because both involve the same phenomenon. The late-Victorian physicist Lord Rayleigh gave his name to the way that electromagnetic radiation is scattered by objects that are smaller than its wavelength. This applies to the particles in the air that scatter sunlight, and aircraft stabilizers and wingtips that are about the same meter-class size as VHF waves.

    The counter-stealth attributes of VHF have been public knowledge for decades. They were known at the dawn of stealth, in 1983, when the MIT’s Lincoln Laboratory ordered a 150-foot-wide radar to emulate Russia’s P-14 Oborona VHF early-warning system. Lockheed Martin’s Fort Worth division—makers of the F-35—should know about that radar: they built it.

    Making a plane VHF-stealthy starts with removing the target’s tails, as on the B-2 bombers. But we did not know how to do that on a supersonic, agile airplane (like the F-35 is supposed to be) when the JSF specifications were written.


    Neither did the technology to add broadband-active jamming to a stealth aircraft exist in 1995. Not only did stealth advocates expect jamming to fade away, but there was an obvious and (at the time) insoluble problem: To use jamming you have to be certain that the radar has detected you. Otherwise, jamming is going to reveal your presence and identify you as a stealth aircraft, since the adversary can see a signal but not a reflection.

    We can be sure that onboard jamming has not been added to the F-35 since. Had the JSF requirements been tightened by one iota since the program started, its advocates would be blaming that for the delays and overruns.


    What the JSF does have is a jamming function—also known as “electronic attack,” or EA, in militaryese—in the radar. It also has an expendable radar decoy—BAE Systems’ ALE-70. Both are last-ditch measures to disrupt a missile engagement, not to prevent tracking.

    JSF’s planners, in the mid-1990s, were close to correct when they calculated that low-band stealth and limited EA, combined with passive electronic surveillance for situational awareness, would be adequate at service entry. But they expected that the F-35 would reach squadrons in 2010, and China’s military modernization was barely imaginable.

    The threats of the late 2010s will be qualitatively different. Old VHF radars could be dealt with by breaking the kill chain between detection and tracking: they did not provide good enough cueing to put analog, mechanically scanned tracking radars on to the target. Active electronically scanned array (AESA), high-power VHF radars and decimeter- and centimeter-wave trackers are more tenacious foes.

    Last August, at an air show near Moscow, I talked to designers of a new, highly mobile counterstealth radar system, now being delivered to the Russian armed forces. Its centerpiece was a 100-foot-wide all-digital VHF AESA, but it also incorporated powerful higher-frequency radars that can track small targets once the VHF radar has detected them. More recently, however, it has emerged that the U.S. Navy is worried because new Chinese warships carry the Type 517M VHF search radar, which its maker says is an AESA.

    None of this is to say that stealth is dead, but it is not reasonable to expect that the cat-and-mouse game of detection and evasion in air combat has stopped, or that it ever will. EA and stealth still do not coexist very comfortably on the same platform, but offboard EA and stealth are synergistic: the smaller the target, the less jamming power is needed to mask it.

    But the threat’s demonstrated agility drives home the lesson that there is no one winning move in the radar game. Excessive reliance on a single-point design is not a good idea, and using fictitious secrecy to quash the debate is an even worse one.

    It's smaller Podsolnukh OTH radar.

    Talking about radars, Russia have now excellent opportunity to record F-22 combat stealth fingerprint caracteristics and could test in what distances could Syrian air defense complexes detect and track F-22 as well as their long range EW radars together with OTH radars if they could track F-22 over Syria, when it is in full stealth in combat mission. I'm sure they will not miss it. When having F-22 fingerprint, F-35 will not be far away, what mean if they will be capable to detect and fight F-22, then they could also F-35.

    New radar and control station "Outpost" is designed to detect ground, surface and low-flying objects and is able to track at least 50 targets at the same time, at a distance of 20 km, and surpasses the range of foreign analogues by 3-fold, and the ability to distinguish between two separate objects is 16-17 times better than foreign systems:

    The new system of defense industry finds the offender for 20 km
    Corporation unveiled radar control "Outpost"

    Russian Radar systems - Page 10 UTK_8909_588

    Combined instrument-making corporation showcased Interpolitex 2014 to develop its concern "Vega" - radar control areas "Outpost", which according to its technical characteristics superior to existing foreign counterparts.

    Control Station "Outpost" is designed to detect ground, surface and low-flying objects and is able to track at least 50 targets at the same time, according to a company press release.

    "Radar" Outpost "- a system of circular scan capable of detecting moving objects at distances up to 20 kilometers - the director of the Department of Joint instrument-making corporation Alexander Kalinin. - Resolution on the range, or the minimum distance between two adjacent commit object is 30 centimeters, which is very good. "

    The structure consists of radar radome, the antenna device scanning, receiving-transmitting unit, a digital processing, and workstation attendant, which is located at the outpost, and may be shared by several local radar sensors.

    "In comparison, common foreign systems have a maximum range of 6.8 kilometers, - says deputy designer general concern" Vega "Victor ivy. - Close to our figures for the maximum range now achieved in the German inventor. But the range resolution is considerably worse: not 30 centimeters, but about five meters. If we in the beam in one direction 60 thousand range of elements, then they - 6-8 thousand, their system cover this area at the same time can not. "

    The system is equipped with a detection function "smart intruder", which allows to distinguish humans from other moving objects, even if he disguises his movements.

    As told Victor Ivy in included adaptive detection algorithms that allow automatically adjust the background changes, such as those associated with the spring growth of grass or falling snow. Previously, experts solved this problem for several days.

    "When you work with the ground surface, and not with the sky, the picture is complicated by the reflection, or background of the earth. It is important that this background, it was possible to distinguish the good man, because background is quite complex - there is grass, bushes, and other objects. When the snow falls, the background characteristics are also changing. On the circumference of 20 kilometers, we have 15 million points that we must accept and track. Now developed an algorithm that can do this automatically, "- said Viktor ivy.

    Today, the system "Outpost" passed all tests and is ready for serial production.

    Control Station "Outpost" is designed to detect ground, surface and low-flying objects and is able to track at least 50 targets at the same time

    This is some great news, so 'Outpost' is capable of tracking 50 low-flying targets at a time, at 20 km distance, and only needs a minimum of 30 centimeters to differentiate between two low flying targets, combined with the Pantsir system to replace Kashtan it could do great service protecting Russian ships from low-flying ASHm swarm tactics. It could also be useful detecting swarming low-flying cruise missiles.

    They could use them in large numbers on ships to protect from AShM's like you said... That being said, I can't find anything on it being naval vessel capable... Do you have anything on that?

    Anyway, these hooked up with a Pantsir or Palash and a 9M100 launcher of some sort would add up to be a very "thick" defense.

    Nothing is explicitly mentioned, however I wouldn't see why it couldn't. BTW another positive feature is that it's capable to seamlessly integrate in to IAD. I could see smaller ships like corvettes with 4 integrated "Outpost" radars in 4 different directions with the ability to track 200 low-flying targets all together, bigger ships like destroyers could have 10 "Outpost" radars and track 500 targets, and aircraft carriers could have 20 of them to track 1000 targets.

    and only needs a minimum of 30 centimeters to differentiate between two low flying targets,

    The thing is that if you have a swarm of anti ship missiles flying 1 metre apart trying to pretend to be one missile... the effective shrapnel radius of most SAMs means hitting one would destroy the others too, but better discrimination of the target is certainly not a bad thing of course.... Smile

    I suspect this radar is a replacement for ground surveillance radar used by ground forces to track enemy ground targets in all weather day and night.

    I agree. This is what struck me the most:

    1. Russia has had/produced Valeria passive radar detection system from Soviet times and this most likely refers to its highly modernized version

    2. Increase in MTBF (maches western radars which might launch its export potential)

    3. Active/Passive version combo where Ring has excellent low lvl charateristic and although I would not exchange 30N6 or 64N6 Very Happy with Ring 96L7 is something to talk about even on mast.

    4. Now look at this madness

    450 miles on a typical fighter radar, and up to 900 km on the AWACS aircraft RFCs "AWACS". Can simultaneously track up to 250 radio-emitting objects with certainty the origin of 0.94, the approximate time of the passive station RTR to the first problem, around 2000 hours, scanning and "tie conditional paths" can take place automatically

    SRTR "Valeria" is able to detect all long-distance communication systems and tactical alignment of NATO countries («Link 11», «Link 16"), in addition, found even altimeter strategic cruise missiles and even ARGSN missiles "air-air" and "air- the ship. "


    What more could one want? Very Happy

    5. While at the same time its precission is astonishing for an passive radar set as though it could guide some active guided missile Very Happy

    6. And what does it do ... huh .... just enjoy reading

    Russian IADS have many similar ELINT passive radar complexes to Valeria, like Kolchuga, Orion, Avtobaza, etc. They all work in the same way to listen for any signal in the air and to triangulate the position of target. Different complexes mean different frequency belts for detection. To be stealth for them, the plane have to turn off everything on board, communications, data links, radar, radio altimeter, IFF,..., but that mean the plane is blind if it doesn't use its radar or links with network to get info for targets from other sources.

    Rogozin was here in Brazil this last week and there has been no news on the press over the outcomes of the meetings, apart from the negotiations for the purchase of Pantsir systems. There has been a rumour that there's a deal between Russia, Brazil and South Africa to have the NG Grippens fitted with this Phazotron's 3-D AESA radar that should've been showed to potential clients during last November. Has anybody read or heard something in this regard?
