Ways to Defeat Stealth

Being able to hide from your enemies and attacking them from behind has been on the minds of every military in the world ever since the beginning of time. With air force, the word stealth and a couple of funny looking planes come to mind. The F-117 Nighthawk was the first operational stealth attack plane in the world. Despite its funny looking shape and design, it was able to deflect radio waves and fly undetected across the sky. Further improvements in stealth brought you the B-2 Bomber and F-22 Raptor, as well as the other planes with stealth features. These new planes will be able to go across the sky and strike their enemies without them knowing what had hit them. This was probably the innovative weapon that everybody had searched for.
But can this magical ability be defeated, or will stealth planes continue to be invincible in the skies?
There is already much talk of a new generation of weapons, and weapon concepts to defeat stealth and many rumours have been debated over on internet forums. I did some research and I will be talking about a couple of these ideas in my article.
Radar measures the time it takes for an electromagnetic echo to return from a target.
Stealth aircraft evade radar by using their shape ad surface coatings to disperse and absorb most of the radar transmissions they encounter.
1) One technique uses conventional radar to search for discintive patterns of air turbulence, because it's very hard to supress air turbulence.
2) Another technique looks for enegry-drops or shadows in radar illumination reflections. This is done by merging information from several ground-based radars, none of which is capable of detecting the aircraft on its own. So basically it's piecing infromation from different radars to form a big picture of where the plane should be.
3) A passive radar system listens to low-frequency radio waves and utilizes high-speed computers to distinguish signals that are bouncing off moving objects in the air. Serbians may have used low band radars to track and shoot down the F-117 in 1999.
4) Stealth cannot be created in every frequency.
I am no expert on stealth and radars, please correct me on any misinformation. Thanks, Michael.
