Would this be possible
A new kind of stealth that instead of just having wierd surfaces it releases eith sonar or rdar waves that its not there. Would it work?
Not at all. The idea of stealth technology is that radar waves do not "bounce" back to the station. Releasing a radar/sonar wave of your own would broadcast that you exist (much like jamming a radio).
Hell, if it 'releases' something that gets back to whatever radar is looking for it, it's obvious there's something there. If a radar is getting back a signal, even a signal from something that tells the radar that the thing isn't there, it's obvious that it's there.
:roll:
Confusing, I know. Can't explain it better.
I think I'll drop it but one last thing I mean It reales radar waves reporting that it nothing was there
*Smacks Lima Beens around*
If the radar gets back a signal it means that there's something there. Even if the signal says that there's nothing there. If there was really nothing, the radar wouldn't get a signal, period.
Those 'weird designs' you mentioned cut down the chance that the signal will ever return to the radar.

Better to be made of a radar-absorbing substance. Either that, or use that substance to cover it.
thanks a ton I've dropped it
Radar is a high-frequency (sound) wave? If something the same frequency bounces back, then it measures how long it took, the size of the amount of waves that came back, ect to get it's position.

Its entirely another thing to try and cancel the radar waves ofcourse....
see this is an example of a noob learning. See! See!

With sonar, you could broadcast out of phase noise, that would cancel out the actual noise and make for an extreemly quiet environment.
And I did not make this up. SAAB has it on one of their passenger airplanes.

It wouldn't be new, and it wouldn't be stealth.
You've just described a jamming system. Either that or a decoy. In both cases, it broadcasts your presence, but (hopefully) prevents the enemy from knowing exactly where you are.

Actually, you'd need to figure out what kind of signals the radar gets when it doesn't hit anything, and send those back. You'd need a really powerful computer to figure out every time the radar searches what that signal would be. I believe Stephen Coonts suggested something along the lines of that in the book Fortunes Of War.

If the radar doesn't recieve a signal back it shows that there's nothing. If he gets a signal it means that there *is* something.

Yeah, that's true. I don't *quite* remember the tech he mentioned, it did cancel out anything when there was nothing else there, but radar will bounce off of clouds and such, right? So on a cloudy day, you'll want to duplicate those signals, because if the radar comes back saying it's perfectly clear, something's wrong.
This is mainly for soanr would it work there?

This is for sound. The same idea should apply to radar, but I cant confirm it.
