it is how the passive radar net works
wheere is the proof. we actually don't believe communist created spam. You have to bring a credible Information. Only pakistanis will believe you on this junk. First shoot down something stealthy, then we will listen to you. why don't u chinks start with shooting down one the japanese F-22A. Please do your self a favor and post this some chinese forum:viannen_10:
that just prove how you are ignorant!
passive radar has been used to detect traditional stealth objects like sub for decades.
it is not strange at all to use passive radar to detect new stealth objects like stealth birds.
Czech developed similar anti-steath radar several years ago,called "volla".
Czech once tried to market radar to Chinese, but failed.
now, the CHinese indigenious radar is ready to export, which exactly explains why Czech failed to market their "volla".
