U.S Naval Institute News (http://news.usni.org/2014/07/29/chinese-russian-radars-track-see-u-s-stealth) reports the Chinese and Russians maybe developing such systems. The present radar systems use high frequency waves for accurately locating an incoming target. Stealth aircraft are designed to adsorb or reflect these wave away from the receiver. It turns out longer wave radars can see the stealth aircraft. The longer wave radar lacks the precision of the high frequency radar, but when the two are combined, as the Russians, Chinese (and US) are doing, you can produce accurate targeting radar. The F117 may have been in a golden age for stealth technology, it will be interesting to see if the F35 arrives to late to be effective against other countries with advanced radar systems.
