I’ve long wanted to do this with an SDR and maybe some simple ML, build a dataset by driving by cars/things with frequencies of interest. Now I wonder if you c

  You can fingerprint transmitters. Antennas would be much more difficult and likely moot. https://arxiv.org/html/2402.06250v1 https://arxiv.org/html/2402.06250v1

    Some transmitters have such a distinct sound that you can identify them with just your unassisted human hearing. Back in my firefighting days, I remember that certain trucks or stations had transmitters where you could identify them from the half second or so of "hum" between the time somebody keyed up the mic and the time they started talking. Using ML / signal processing stuff on a computer, yeah, you can probably get pretty fine grained at discriminating these things.
