I built an open-source tool to monitor naval bases using free satellite radar, no AIS needed

Hey guys! I previously posted Netryx in this sub and received a lot of love for it. It recently hit 1k stars, so thank you for the support! I’ve been working on a new project called Keelix. It uses free Sentinel-1 SAR imagery to monitor naval bases without relying on AIS data. By comparing satellite passes over time, Keelix detects ships at individual berths, tracks potential arrivals and departures, flags unusual activity, and generates before-and-after radar comparisons with confidence scores. It also has an experimental feature to search coastal waters for carriers after they leave port. I tested it against Norfolk Naval Base over 12 months. It detected around 65% of ships, with approximately 95% of detections corresponding to real ships. Estimated counts were generally within one or two ships of reference imagery. The system uses signal processing, not machine learning. There are limitations, of course. It can’t identify individual ships, ships can overlap in imagery, and movements between satellite passes can be missed. So far, I’ve validated it against one base.
