Basically you're right... Operators just control the rotation speed of the antenna in RS, decrease or increase the antenna rotation speed. Please, do a bug check - make an scenario in Hungary with zig-zaging target, and take it in RS, than check if it does follow the target again without transmission.... If so - please, report in the Bugs topic... You could do the check with other systems also.... thumbsup

Thank you for answers.
Tested. You are right - the system does not follow the target when it changes its course. It seems we have a really good tracking operator smile

10.05.1972... Extremely lucky pilot...

Quote:
Nonetheless, it would certainly be interesting to hear what happened to the first MiG-killer" of the day, namely Lt. Court Dos- which was punished by escorting A-7s - on the same afternoon. At 3:15 PM Dos and Hawkins escorted a pair of Iron Hand a-7s north of Hon Gai, when Doss RWR showed signs of a SAM launch from the West. Dos informed the A-7 pilot, but the later - only 300 meters away - said his equipment showed no such signals. As luck would have it, the late afternoon sun sat low in the sky to the west, and its rays were diffused by a bank of haze. Suddenly, Dos saw two SAMs, busting out of the haze in our nine oclock, doing about Mach 3." He rolled the Phantom on its back and pulled into a dive trying to outmanoeuvre the missiles, but the robot weapons corrected to a new collision course. Dos rolled out and pulled into a maximum G climb, while missiles readjusted their trajectories and continued after the fighter. Now, the SA-2s were too close for any further evasive manoeuvring and closing fast: One missile came past the nose, the other went over my canopy. It looked like a killer shot. Those missiles had 280-ound warheads, they had us cold. They were so close I could see the control surfaces moving. I gritted my teeth and waited for the explosion. I was looking at em, tensed up, ready to die. And they just continued on past, they didnt get off!"

They do this in Vietnam with SA-75 missiles....

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.

True... About SR-71 - it has (since 1972 I think) a possibility to "interrogate" SA-2 missiles and thus find which launch is fake or real.

nope
There were a FOIA CIA document describing the measures taken against the Dvina.
One system was recording, and with delay, retransmitting missile guidance command signals.
biggrin

I shall dig to find it...

This is for A-12.... SR-71 got different (and more capable system). Part of it (Special Elint Beacon Receiver - SEBER), known as System G was introduced in 1972...

That's all... It is from a book about SR-71...

EDIT: Here the veteran described a SAM launch and beacon interrogation:

There was a nice debate between Hungarian exFCOs, about this switching...

http://youtu.be/uiOkFoYUCYw?t=3m12s

... what is your educated guess?
What is this Dvina FCO switching on?
