Starlink version 3 has the potential to be the most powerful SAR and spy satellite constellation in general with minimal hardware modifications. For Starlink version 4 or Starlink that are radar optimized by SpaceX, they could be even more powerful. https://www.youtube.com/watch?v=jbp3kdJZ1_A Starlink signals can also be used to build passive radars by others: Starlink-Based Passive Radar for Earth's Surface Imaging: First Experimental Results https://ieeexplore.ieee.org/document/10620445 Remote sensing and target acquisition with Starlink satellites https://www.fhr.fraunhofer.de/en/sections/Multifunctional-RF-and-Radar-Systems-MFR/Remote-sensing-and-target-acquisition-with-Starlink-satellites-JB2022.html Germany has built a passive radar demonstrator that tracks targets using radiation from Starlink satellites opportunistically. https://www.army-technology.com/news/germany-demonstrates-passive-radar-system-using-starlink-satellite-radiation/ #SpaceX #starlink #satellites #space #dsp #radars #technology
