Do radars put a significant drain on performance? I'm planning on covering a gigantic area with radar outposts, but I don't know if that would kill my UPS.

I've never heard anything of the sort.

You could make a named save, build 100 radars, and run them down a line and see if that hurts anything. If not, then you should be good to go.

Radars don't hurt UPS. Gigantic explored areas do hurt UPS, especially if they are populated with biters.
