But that was jamming of the wide-band antenna missile beacon channel. Its described in detail in page 6 of the SA-2E Advanced manual by Vintorez.
They attempt jamming of UPLINK and DOWNLINK transmitions...
As far as I know, generally they jammed the missile Beacon signal (Downlink). I know only that the A-12/SR-71 was trying to inject false missile guidance commands (Uplink), but it was a futile attempt.
