The AWACS (& other airborne) radar platforms throw
another interesting complication into the mix.
They are moving too.

To compute the location, (in relationship to the receiver,)
of a moving object reflecting a stationary transmitters signal
would be easy compared to computing the location,
(in relationship to the receiver,) of a moving object
reflecting a signal from another moving object.

The location of the transmitter (AWACS, etc) could be
determined by a active radar, but lighting up a USAF AWACS platform
is akin to standing in the middle of Paris Island yelling "Jarheads are fags."

The location of the transmitter (AWACS, etc.)

Since that platform is a transmitter, it could also be located by a passive receiver tuned to it's radar frequency.
That receiver site would need to be able to adjust frequencies quickly,
and be able to send it's results in realtime.

Passive is going to pick up the location of any radar source. We just keep the AWAC's back out of harm's way. I am sure a sophisticated Russian radar would have no trouble with a moving radio source. To me it would seem like you could get more info rather than less with several radar sources moving back and forth parallel to the line of resistance. The airwaves would be flush with signals in a conflict area anyway. I am sure the Russians capitalize on every twist we can think of here.
