Stealth aircraft, such as the F-22 and F-35, are designed to evade conventional radar systems located on the ground, but they are detectable from space. Chinese scientists have successfully used Starlink satellite signals to detect a stealth target during a radar experiment in the South China Sea. This new method could be applied to future military technology and stealth aircraft detection, reports the South China Morning Post.
In the experiment, a DJI Phantom 4 Pro drone, roughly the size of a bird, was used to simulate a stealth aircraft. The radar cross-section of the drone was similar to that of actual stealth fighters. But instead of relying on traditional ground-based radar emissions, the drone was detected by analyzing electromagnetic signals from a Starlink satellite passing over the Philippines.
