Had not heard of that ... I think all we did was cause a lot of static on local radio and TV ... the frequency range that the ECM targets are fairly specific. The output of the ECM equipment is designed to analyze and then copy and then send out a more powerful return signal just a few milliseconds behind the weak signal that the SAM radar is expecting to see from a target. That very strong signal that sneaks in right behind the weak (true) signal can and does confuse the targeting software controlling a SAM. That is what the AWAC’s would be looking for ... new radar frequencies used to launch and guide SAMs.
AWACs might have some capability to do that, but the specialists in that sort of thing are the RC-135U COMBAT SENT
And the RC-135V/W RIVET JOINT.
Pictures are a bit out of date, the birds have been re-engined with CFM-56s (F108-CF-201), which are much larger than those shown. There are only two RC-135Us, and 13 RC-135V/W aircraft. All are assigned to the 55th wing at Offutt AFB, near Omaha. They deploy worldwide of course,
