"In recent days, he used radar data from a satellite to detect jamming in Iran. While the BBC has not independently verified this data, Gorman says that jamming devices leave a trace of the interference they cause in radar signals, allowing him to reveal occurrences of GPS-jamming around the country."

(I suspect this is Sentinel-1... will have to go look).

@ai6yr
I wonder if that is what happened when Chinas fishing vessels appeared in a line.

Can Sentinel-1 Detect GNSS Jamming? New Evidence from Temporal Baseline Analysis

We previously investigated whether Sentinel-1 C-band SAR (5.405 GHz) could detect radio frequency interference from GNSS jammers operating at L-band (~1.

@ai6yr I've known Sean for a couple of decades. I was on the board of one of his many startups. He does fascinating work on all things spatial.
