Infrared (heat)
Some analysts claim infra-red search and track (IRST) systems can be deployed against stealth aircraft, because any aircraft surface heats up due to air friction.[9] These analysts also point to the resurgence in such systems in several Russian designs in the 1980s, such as those fitted to the MiG-29 and Su-27. The latest version of the MiG-29, the MiG-35, is equipped with a new Optical Locator System that includes even more advanced IRST capabilities.
Wavelength match
The Dutch company Thales Nederland, formerly known as Holland Signaal, have developed a naval phased-array radar called SMART-L, which also is operated at L-Band and is claimed to offer counter stealth benefits. However, as with most claims of counter-stealth capability, these are unproven and untested. True resonant effects might be expected with HF sky wave radar systems, which have wavelengths of tens of metres. However, in this case, the accuracy of the radar systems is such that the detection is of limited value for engagement.
OTH Radar (Over the Horizon Radar)
Over-the-horizon radar is a design concept that increases radar's effective range over conventional radar. It is claimed that the Australian JORN Jindalee Operational Radar Network can overcome certain stealth characteristics. [1]. It is claimed that the HF frequency used and the method of bouncing radar from ionsphere overcomes the stealth characteristics of the F-117A. In other words, stealth aircraft are optimized for defeating much higher-frequency radar from front-on rather than low-frequency radars from above.
There are unsubstantiated rumours that Australian civilian air traffic controllers have tried to contact, in-air, high-altitude, F-117A pilots crossing the Australian continent without airspace clearance due to datafeed from the JORC. Apparently there was no response from the pilots.

i want to see the US take the f-22
and test it on Russia its self
right now the f-22 is untested in combat and against a real threat against it
since from this prospective the US just screws with countries with an air defence network which is outdated or complety obsaliete which any 3rd world country could fly into.
and how much would you be willing to bet on that?
last time i checked the russians spend less and create just as formidble defences
also the f-22
is more then 20 years old in design as it was built for the cold war
