Abstract:

Mega-constellations of low earth orbit (LEO) satellites for global Internet services, such as SpaceX’s Starlink, have now materialized. Similar to radio astronomy, using the microwave signals from the LEO satellites, it is possible to retrieve things in the sky, e.g. rainfall, flying objects, and space debris. However, the sky is vast. How far away can a ground detector detect? In this talk, the feasibility of flying object detection with opportunistic signals from the LEO satellites will be discussed, along with tracking and shadow profile retrieval.

Biography:

Defeng (David) Huang received the BE and ME degrees in electronic engineering from Tsinghua University, and the Ph.D. degree in electrical and electronic engineering from the Hong Kong University of Science and Technology (HKUST). He joined the Department of Electrical, Electronic and Computer Engineering at UWA in 2005. Before joining UWA, he was a lecturer at Tsinghua University. He pioneered the inter-disciplinary research on detecting flying objects using signals from LEO satellites.
