Depending on your definition of it you could argue that ESM has been a thing since they had radar detectors at the end of WW2.
This is just supposition on my part but I would guess for an ESM mast, bearing would probably be pretty important as well as some type of analyzer to gauge signal strength and probably give you some idea of detection values i.e. if whatever is bouncing these radio signals off of you is getting a strong enough return back to have pin-pointed your location. I'd say all that would come before actually being able to figure out an exact location where emissions are coming from.
