Hello Eric,
Will radar even work in space? If so, what's the range,
and how would it work?
Radar does indeed work in space. The Gemini mission used radar to practice
spacecraft rendezvous in preparation for the Apollo lunar landings. As
well, with the actual landings, radar was used during the descent and ascent
phases. It was the ascent radar being accidentally switched on which caused
the infamous 1201 and 1202 alarms during the descent phase of Apollo 11.
As to the economy of using space-based radar to search for NEOs. As others
have pointed out, nahhh.

Richard, List,
Since smaller meteoroids and asteroids are nearly undetectable in space,
and we're currently searching optically with telescopes. Is it possible to
detect meteoroids/asteroids with space based radar?
Will radar even work in space? If so, what's the range, and how would it
work? Do we have something like this?
I know we have space based weather radar satellites, but what about
pointing them into empty space to search for asteroids?
Sorry if this is a dumb question... Just curious.
Regards,
Eric

Small chunks of Vesta in earth crossing orbits, say 10 meters in

detected a few days before impact, if at all.
