This first part is the overview. In later postings I will go through more detailed block diagrams of the different parts of a passive radar system, provide example data, and give some Python ...

Researchers at the Fraunhofer Institute for High Frequency Physics and Radar Techniques FHR are breaking new ground in avalanche detection. Passive radar—which uses signals from the new Starlink ...
