A kind way of putting things, falconfixer...

My take from just the title of this thread alone...BULL$HIT!

Beers and MiGs were made to be pounded!

Some people said that the sound barrier would never be broken also. Now that is "real bullshit". Very Happy

Has anybody thought about this? If in fact that plasma stealth where in use, and somebody was looking for a aircraft that used plasma stealth technology, why not just look for a hole in the sky where radar waves disappear? To me that seems like a easy way of detection.

Oh yeah, just thought of this to check this out these guys call this optical camouflage pretty neat stuff like preditor in the movie: http://projects.star.t.u-tokyo.ac.jp/pr ... xv/oc.html

Yes, that is a method of detecting stealth. Advanced DSPs using the signals from radio stations or other longer wave transmitters can detect stealth aircraft. But even if you know there is a stealth aircraft in the area, if a microwave band seeker head can't see the stealth, what good does it do you to know a stealth aircraft is around? I suppose you can head for the air raid shelters...

Yeah - that will help with bunker buster bombs....you'll just die tired - but at least you'll save the gravediggers some work - prefab gravesite.

Would this ion-system affect you IR-signature?

In some lab setups, the plasma remains fairly cool close to room temperature. That’s why they are called "Cold Plasmas". However, since the electrons have such a tiny mass, a few degrees K results in significant kinetic energies. Of course, this depends in the condition, but some cooling is usually applied due to heating from electron impact. For example, inductively coupled plasmas have a metal coil antenna and it is practical to flow water through it. I've also used microwave coupled setups in which we simply blow compressed air to prevent the dielectric enclosure from cracking.

I would imagine that heating would not be a major concern for hypothetical "plasma stealth" systems.

Hi FalconRed,

I have a hard time imagining how to do this without covering the sky in tin-foil. Could you tell us more?

I personally think multi-frequency and/or burst emissions would do the trick. But then again, nobody really knows how sophisticated such systems might become. If ever...

Well I guess I see it like this. Kind of like how we detect enemy SAM sites. Aircraft know there is a RADAR wave there targeting them. So if you have one RADAR site trying to locate the aircraft(actively scanning) and another site looking at those RADAR waves.

I guess I see it as that you would have what would apear to be a hole in the sky. Or like if you shine a flash light at a mirror it reflex the light some where else but go's past on eihter side of the mirror, if you looked at the light waves you could see light going past the mirror on either side or reflected but would be missing from behind the mirror. And knowing where your light waves should be they aren't .

Maybe I got this whole thing wrong... just an idea.

Hi FalconRed,
I think I understand. You would need the object you are attempting to detect "sandwiched" between the transmitor and the detector? You would probably need a very powerfull transmitter flying high (easy to shoot down?) and an expensive array of detectors over probable flight paths. The opposite would work too but it would be even more expensive.

The problem I see with this is that the location of transmitters are known, since it is public. Public comunication infrastructure is one of the first things to go in a war. Maybe this is useful against a stealth raid?

One thing that people continually overlook on this site, which you nailed Pat, is the fact that it IS known where the transmitters and dishes are. Wild Weasels are sent in first, to deal with these sites. When they're history, it makes it harder for them, and easier for our guys to work.

The concept of plasma stealth is an urban legend. Cylon got it right. To create a plasma field which can cover a fighter, you'd have to put out a high level of detectable energy.

Why risk pilots lives? Public broadcast infrastructure is fixed; cruise missiles would do the trick Wink

They can also get shot down easier than an ARM.

I'd hate to know that we're wasting an expensive Tomahawk or an ALCM on a few microwave relay towers and a remote dish. The cost of an AGM-88 is a little more equal to the price of the antenna/dish array. Also, cruise missiles don't know when mobile com centers are on the move. An F-16CJ pilot does. Because of this, Wild Weasels will be a necessary weapon for a long time to come. I anticipate a remotely flown UCAV to be the CJ/DJ's replacement.
