The Chinese are building a ghost-imaging spy satellite reportedly capable of seeing — and tracking — U.S. stealth fighters.
“Existing camouflage techniques – from simple smoke bombs used to hide tanks or soldiers on battlefields to the hi-tech radar absorption materials on a stealth aircraft or warship – would be of no use against ghost imaging, physics experts said.
“Quantum ghost imaging can achieve unprecedented sensitivity by detecting not just the extremely small amount of light straying off a dim target, but also its interactions with other light in the surrounding environment to obtain more information than traditional methods.”
If successful, the satellite could detect and track stealth aircraft, such as bombers, taking off from airfields even at night. B-2s mostly are launched under the cover of darkness, in part to avoid high-definition optical cameras on spy satellites. It’s successor, the B-21, is under development and will feature improved, but similar, technologies that currently make the B-2 invisible to sensors.
The report said the Chinese expect to have the satellite in orbit within a decade. [source]
