I have, in the past, wondered how practical it would be to take a highly-directional antenna and a camera mounted on a computer-controlled tripod head and then pan the thing around for a bit and create an image with a heat map overlay showing where the signal is strongest. I was thinking about making a map showing WiFi networks.
If you have some fancy RDF antenna array, which I imagine that military signals intelligence people do, might not even need to do the panning.
Even just one additional sensor if they’re directional. Even if optical camouflage of broadcast equipment might work in the short term, I don’t doubt that Ukraine will find a way around that relatively quickly. The Ukrainians are really good at this and, well, it’s broadcast equipment.

You’ll need a big dish or phased array to get that kind of directionality, but it’s doable.
If you wanted to do radio stations, which are on longer wavelengths, it probably isn’t anymore.
This sounds very similar to this project from The Thought Emporium
Add 2 more sensors and you can triangulate. Fly them around on drones and you could search the countryside
