Good question there "Desert Dawg", and my answer is I don't know. I didn't even think it was real but apparently it can be done.
I think . . . but don't know for sure, that differing designs of turbine blades can give off different pulses and perhaps what they're reading is
that pulse moreso than the rpm levels.
Regardless, your initial post about reading a signature from an engine is right on the money and how they do it is probably information they're not
gonna release for a while.
As a small matter of interest, I read several years back that fighters have an optical ID system in the cockpit that can tell the pilot just what
he's looking at from about 50 miles out.
Gyroscopically stabilized I would imagine.
Gotta be tough to keep track of all the systems, threat warnings, radar etc. as well as navigate and fly the airplane....
