Chinese researchers have found an innovative way to use SpaceX Starlink satellite constellations to detect aircraft, like stealth fighters, passively. According to Chinese media, this was achieved by effectively detecting the “shadow” of an object between the detector and the electromagnetic radiation emitted by the satellites.
The team behind the discovery reportedly used a DJI Phantom 4 Pro drone to simulate a stealth fighter and conduct their experiment to achieve this. This drone was chosen as it has roughly the same radar cross-section as something like an American F-22.
If true, the experiment, conducted off the coast of Guangdong in the South China Sea, could revolutionize stealth aircraft detection. The Chinese government’s State Radio Monitoring Centre oversaw the experiment, and the results were peer-reviewed before publication.
