Are they using the new Dominion Early Warning System? Out of 5 air defence radars, 23 of them reported a missile launch.
FWIW, if a missile were launched from Iran (most likely source) or Russia (highly unlikely) into Ramstein, the first indication would be on SBIRS (Space-Based Infrared System), followed quickly by detection by BMEWS (Ballistic Missile Early Warning System) RAF Flyingsdale Moor. BMEWS Flyingsdale is an RAF show, but U.S. built and paid for. What the U.S. gets is real time data courtesy the RAF (who are very good at what they do.) I don’t think there is any local radar that would see a thing, and I doubt there are any inceptors that could do anything about it. We were going to place interceptors in Eastern Europe until Obama nixed it.
