I've visited this radar installation - of course, as another poster pointed out it was an OTH missile detection system. But a fun conspiracy theory floated by my guide was that this installation was intended as a Soviet weather control experiment. The evidence for that, such as it can be considered, was that allegedly there were supposed to be 12 reactors at Chernobyl, not just the famously exploded Reactor 4, which would have been an immense amount of energy production capability for one single location. Additionally, the nearby Pripyat was inhabited by the brightest of the bright, most elite of the Soviet population in an already highly secret portion of the Soviet Union. Who better to attempt that sort of endeavor? Plus, what powerful government doesn't wish it could control the weather?

Whether or not it's true, it clearly didn't work. But it sure is fun to think about.

edit: typos

Also, while I was there I picked up some forgotten artifacts in the form of old computer operations manuals, including one for the Russian ES EVM, which was a copy of the System/360. I scanned all the pages, maybe it would be interesting some people here: https://chernobylbooks.netlify.com/
