Passive Bistatic RADAR Using Spaceborne Sentinel1 Non-Cooperative Source - GRCon21

Explore passive bistatic RADAR techniques using a spaceborne Sentinel1 non-cooperative source, a B210, and a Raspberry Pi4 in this conference talk from GNU Radio Conference 2021. Learn about the experimental setup for receiving signals transmitted by satellites illuminating Earth areas, with a focus on mapping range and azimuth reflector distribution. Discover how to overcome challenges associated with mobile spaceborne sources and achieve quantitative imaging of reflectors using minimal equipment. Gain insights into Synthetic Aperture RADAR processing and its educational potential, leveraging freely available Sentinel1 C-band RADAR records from the European Space Agency. Understand the principles of cross-correlation for range estimation and azimuth resolution in passive bistatic RADAR systems, and explore the applications of this technology in various scenarios.
