a very good technology that the Soviet Union developed which punches above its weight in situations like the Ukraine war because the mobile radars are hard to suppress with these methods

I have seen a huge number of Buks in various conditions in video footage from the war, one of them was scurrying around the 'suburban' areas of Kiev. I wouldn't be surprised if some of the early missile hits on residential buildings were something like this that failed to lock on

Ukraine has a lot of Buks, it has a handful of these too
https://en.wikipedia.org/wiki/S-300_missile_system
on paper those are better than the Buk but Ukraine doesn't have so many and I think the Buk is a "cheap and cheerful" convivial weapon like the AK-47 that does great when exported.
(Both the Buk and S-300 are a lot like the US Patriot missile system in that they are comprised of a number of mobile units such as command posts, radar, missile launchers, etc. The Buk however has a configuration where the radar and missile launcher are colocated on the same vehicle and I'd guess that configuration works really well under rough conditions with less trained crews.)
