That's textbook radar theory - see:

Provided that you have enough EIRP (EME rig?), I would expect that 6m or 2m
would probably be a good choice of band, since shorter wavelengths are more
likely to undergo optical scattering, which might not be in the direction of
your intended RX.

On this subject, have any hams tried using the ISS as a passive RF
reflector?
