Tactically, this is a dubious technique, even at the speed of light.
Assuming the antenna is the 360 deg rotating type, for now. The faster the rotation, the more accurate target update
AFTER lock. On the other hand, the slower the rotation, the longer the 'dwell time' of the beam on a body which improve the odds of acquiring a target in the first place. Surveillance radar rotation speed is best below the mid-20s rpm, something like between 10 - 25.
ATCR 33S provides en-route and terminal management area services. It is an S-band air traffic control radar. The ATCR 33S is designed to be compliant with the international standards for PSR sensors. Functional and performance characteristics meet the requirements issued by ICAO and EUROCONTROL.

• Automatic antenna beam switching for ground clutter suppression
Surveillance antenna rotate at 12-15 rpm. Targeting antenna doubles or more that. But the Targeting antenna depends on the Surveillance antenna and the Surveillance antenna is the one you turn on/off in trying to escape SEAD. In SEAD/DEAD, we strike whichever transmit.
But when people thinks on/off, they think literally on/off. That is
NOT how it works. Can you lock on a body with just one rotation? Yes, if the body is on a fixed test pole. But if there is a spatial-time translation body, fancy language for moving, you need several
SECONDS or even
MINUTES of rotation for the radar computer to calculate where the target is going. That is what they meant for on/off.
To you, I am a moving body, but to me, you are a fixed body. That mean your Surveillance and Targeting radars may need up to several minutes to lock on to me, but my HARM needs just a few
ROTATIONS, not time, from you to acquire you. So if there are SEAD/DEAD fighters over you, any of them can get to you in short order to moment you transmit.
Here is the Pantsir...
Pantsir-S1 (Russian: Панцирь-С1, NATO reporting name SA-22 Greyhound) is a combined short to medium range surface-to-air missile and anti-aircraft artillery weapon system produced by KBP of Tula, Russia. The system is a further development of SA-19/SA-N-11 and represents the latest air defence...

Reaction time: 4–6 seconds (including target acquisition and firing first missile),
My HARM need just one second to detect you. I may need to maneuver to get into a favorable launch position, but essentially, I got your ground position. And no one does SEAD/DEAD better than US.
