The Israelis effectively used a similar tactic against Syrian air defenses in the 1982 air campaign over the Bekaa Valley, using Pioneer drones to trick the Syrian SAM crews into turning on their targeting radars before Israeli Wild Weasel's swept in to take them out.
I wonder if the Russians have any countermeasures for this sort of tactic.
