Use bi-static radars.

One is to passively receive signals that the aircraft is emitting anyway. Examples include RWR, IRST, optical, magnetic anomaly detection, or acoustic sensors.

IRST Far as i know IR sensors do not give any signals at all…. RWR if going by stealth doctrine should also be passive or LO, Optical limitations unless done using algorythm, Acoustic sensor would pick up too much clutter from the surrounding and the pz’s currently around cannot provide the sensivity. MAD thats something ive seen in some movies but i am not sure how many countries can afford to put those sats into space.

The other is to emit a signal that you bounce off the target. Examples include radar or laser ranging/LIDAR.

Lidar/LADAR still under development closest workin ive seen (mind u i dont work in defence so i cant coment on whats not shown) is a replacement for the F/A-22 radar, and also addition to maybe the B-2 or other US stealth planes.

There are various possible methods of detecting stealth aircraft. UWB radars show some promise in this area, and the USSR invested a lot on this technology. An anti-stealth UWB pulsed phased antenna array was under development, ultimately cancelled on the collapse of the USSR.

Was an article sometime back, i even posted it on one of the other threads in the forum, basically US is worried because a lot of the older radar sets can detect Stealth, only problem is filtering out the garbage and presenting a clear picture.

Weather satellites could be used to detect pressure variance in the atmosphere and since the Horse shoe vortex in principle never really dies theoriticly (since you cannot creat or destrow energy to and from nothing it must go some where etc etc, the Horse shoe vortext generated by an aircraft last a very long distance.)

you should be able to trace a flight path of the Stealth aircraft.

Bi static ! woohooo

first time i heard some one mention this on the forum! finally, people start to realise that stealth is not Zues’s bolt.

If you look at the test firing Video, you can see that the some of the systems have a Two part barrel, where in the first part houses the metal storm amo, and fires it, and the second part with the exit is seperate.

As for acuracy, Their is a minimum barrel length iirc you need to stabilise and guide the projectile to its course after that any extra length of barrel is superfluous.

Hypersonic engines, eh? Shouldn’t they be concerned with making the Kaveri work first? 😀

Yup they should!

But also to note is that the SCARMJET does not pose as many manufacturing problems as a Turbofan/Jet. 🙂

I wonder if it would work on a Gefore MX-200 🙁

I hate being skint! :'(

How are the aircraft? I saw the back it didnt seem to have as many varients as i thought it would have.. Not from the makers of IL-2 anyways.
