None of them remotely resemble an E190 though, which is about 50x the size of a cruise missile, communicates effectively with air traffic control and broadcasts ADS-B signals telling you what it is (at least when you're not jamming it...)
You're also making the assumption here that it was a modern Russian system. This wasn't exactly close to the current fighting, its entirely possible this radar was manufactured in the Soviet Union. I don't think those receive a lot (or any) civilian broadcasts.
People do like to provide their very important opinion completely oblivious what Grozny is farther away from eg Crimea than Kiev.
