Gastreferat von Prof. David Huang, Australien: Sky Fence - an Idea Whose Time Will Come?

The concept of using microwave links for object detection dates back to the 1930s but has seen limited exploration. The U.S. Space Fence project uses different technology to track space debris. With the rise of satellite constellations like Starlink, more microwave signals can be used to detect airborne targets without dedicated transmitters. Recent research shows that a network of low-cost ground receivers could create a "sky fence" for air traffic surveillance.
