Imitative deception was often encountered but never, if ever, effective, albeit confusing at times. This is based on having reviewed some 200 or so reports of attempted deception.
Somewhat related, on a Pearl/Yoko transit of the Connie, we placed a radar, identical to the Connie's, on the DLG running nothern screen for the carrier, 150 - 200 miles out. When the expected overflight by Petro based TU-95's were inbound, the Bears identified the DLG as the carrier (heavy overcast), they made their A/S missle run on the DLG, declared it a success and reported a simulated kill of the carrier. Bugged out home without getting with 250 miles of the carrier.
