Passive bistatic RADAR using spaceborne Sentinel1 non-cooperative source...
summary
Demonstrates passive bistatic RADAR using Sentinel‑1 as a non‑cooperative C‑band source with B210 and Raspberry Pi4 capturing dual‑channel IQ at 30 MS/s (or single channel ~56 MS/s), storing ~50 s to catch a ~5 s useful burst; uses two antennas (helical + horn), decodes Sentinel‑1 telemetry/PRI, and performs correlation plus 2D FFT to recover range and azimuth maps at a few‑km range — reproduces clear features (La Défense, Eiffel Tower layover) and publishes code on GitHub.
