Thanks Hpasp for answer. And do you know if SA-10 with semi-active guided missiles (5V55R etc.) has any solution for it? I suppose that older command guided 5V55K could overcome it like SA-2 and SA-3.
The S-300PS/PMU (SA-10B) has manual target tracking capability...
(3 similar indicator at the bottom right)
... but it can track only 1 target at one time.
Generally its a better idea to similarly track both incoming Weasel and launch 2x2 missiles parallelly against them.
With the 5V55R missile 75km range and Mach6 speed, can easily outpace any HARM.
(still have 4 empty channel for incoming HARM or other targets)
