Where'd we put 'em? US to buy Stealth bomber detecting radar

The one country that surely doesn't need to find out where Stealth bombers might be is buying a radar system that is claimed to be able to detect them. The USA is reported to be negotiating to buy a set of Vera radars from the Czechs, the quid pro quo being that a deal to sell them to China does not go ahead.

Vera is the successor to the Tamara radar system, which has been alleged to have been responsible for the loss of an F-117 in Kosovo. This was also the subject of a panic two years ago when it was suspected two systems were among the many fiendish toys that Saddam Hussein had acquired. As these appear not to have shown up in Iraq, we can presumably carry on panicking about who else has got them.

The rationale behind the current proposed US purchase is that the US wants to test the radar's effectiveness. But it is also reportedly concerned that China could use the system to detect US ships and aircraft off Taiwan. The Chinese deal was worth $55.5m, but the Czech government is now
expected cancel the export licence. Proprietors of suspect countries wishing to earn commission from future Vera sales to the US government should presumably contact Czech weapons company Thomas CZ, and remember to write a large cancellation fee into the contract.

1. Radar that looks for gaps in the field

2. In theory Old soviet long-wave radars from 60's (like P-18) detect stealth aircraft quite well

3. Technology behind it is still very immature

This is a bit old news. The US has known of 3 radar systems at least that have persistently picked up stealthy aircraft. Vera and 2 x Australian designed radar systems.

Hence why they are looking at Vera and why they have signed a technology sharing agreement to be part of future development of the 2 Austn systems.

The technology is only immature for those who haven't built systems that can do the job. :D:

lol, buying from others... why America dont make its own?
You're assuming that they don't have their own capability. Thats a bit dangerous to assume. You buy systems to see if there is anything else that has been developed - or to see if you can recognise your own technology as part of the package.

When the Y2K crisis was on, the US emergency teams called in by the Russians to help stabilise the timeclocks discovered that they were using 1950's-60's US technology. From there they were able to establish who was the most likely source of the transfer, and they also knew the technology limitations.

To be blunt, thats a daft thing to say. At a military technology level the US makes most countries look like cavemen - that doesn't mean that they have all the technology and all the answers.

It's smart operating - not stupid. OTOH there are countries who pretend to have capability when everyone knows they don't. Better to be open than pretend and then look an idiot.

No I am not assuming that they dont have technology. Infact America is most advance country in defence technologies. I was just amazed why America is buying from others? now I understand why

Scientists create device to see invisible aircraft

From Kalyan Ray
DH News Service
NEW DELHI, July 28

Uniquely coating two glass slides with some chemicals, Indian scientists have come up with a memory storage device, which is capable of seeing "invisible" aircraft used in warfare and can be used in the heart of future target tracking devices.

After four years of diligent research, a team at National Physical Laboratory (NPL), here under the Council of Scientific and Industrial Research (CSIR) have been able to develop the memory storage device which is superior to existing storage devices as it can store images up to one year. The NPL team got patents on the novel system in US, Japan, Germany UK and South Korea.

Using the NPL device, Instrumentation Research and Development Establishment (IRDE) a Defence Research and Development Organisation (DRDO) laboratory at Dehradun, is working to create an improved target-tracking equipment since the indigenous system is capable of seeing the invisible.

Many nations today use aircraft coated with a radar absorbing paint that make such planes invisible to the radar. "But our device converts invisible images into visible images making these planes visible.

It can see throughout the spectrum — from ultraviolet to visible to infrared range — which is an added advantage," NPL team leader Dr Ashok Biradar told Deccan Herald. The system identifies the planes within a fraction of a second.
On the civilian side, the device can be used for storing holographic images, Dr Biradar said, adding that the commercial potential of the application had not been explored so far. The device runs on one pencil battery and cheaper than semiconductor-based storage devices used in computers.

To prepare the storage device, two-glass plates were coated with a chemical called indium tin oxide. On the coated glass plate, a second coating by a polymer was given. A spacer is used to maintain a tiny gap between the two plates.
But what makes the entire system unique, is a grooving which the scientists were able to create on the polymer surface by controlling the polymer formation and manually rubbing the material.

“The uneven grooves and the thickness of the coating are the two vital components of the storage device. A slightly thicker coating than what is normally used leads to the memory effect while the grooves hold the images that can be seen on a display,†he explained.

For image conversion the optical storage system needs to be integrated with a chemical known as ferroelectric liquid crystal.
The problem area is lack of repeatability as the team has failed in repeating the particular pattern on the polymer by manually rubbing the surface in 90 per cent cases. But NPL is importing a machine that scientists feel will do away with the uncertainty by mechanically rubbing the surface in an orderly fashion.

Yeah how can you test it without Stealth AC????
However its a great breakthrough fro india.

ahh people please. BAE has a solution for Non Radar lockable WVR and almost WVR targets that its going to put on the F-35. the technology basically works on visually identifying targets through a specialized Visual acquisition device mounted on the lower front part of the AC.

Re: Anti–Stealth Radar

south africa had developed a stealth drone known as flowchart2 specifically for testing stealth characteristics and radar detection abilities,india can use them for testing heir radar.

Re: Anti–Stealth Radar

I don't think this NPL device is for use in radar systems, it's a visual detection device. It's not going to see anything out of visual range.

It's usefulness would be in tracking objects that could not be locked on with radar. i.e. for targeting control in visual range only. It's basically a broad spectrum "window".

Not saying it has no uses, just not for radar.

it's just a broad spectrum window that would replace IRST's most likely.Irrelevant since radar guided AAMs are always increasing ranges not to mention DEWS are proliferating. It's not really hard to build such a device, great for surveillance though.:hul

aren't all these stealth radars simply disposition based radars, anyone can accomplish that. It just takes time to integrate the individual components, ie the distributed components. I recon now days this can-be done with ease there's plenty of skill in the commercial industry, geographical Information system is a norm.
I believe you could augment a Stealth detection system in the current fleet of E2s and E3s all the components are there, they share Live data in real time, they all have GPS systems, it would be one heck of a project if accomplished.
