That would be no. We actually have privately owned non-governmental space radar in several countries now due to the increasing commercialization of space. Civilian radar can now pick out things the size of a child’s lunchbox in orbit and there is pretty much complete coverage of anything that’s actually in low to high Earth orbit.
There are, however, still some gaps in coverage the closer you get to the earth due to lack of land surface to put a radar on. The 60s manned missions were usually planned to maximize coverage by terrestrial stations as the craft came down from orbit.
LOL....didn’t realize I needed to add the /s
