The relationship is cT/2, where c is the speed of light, and T is the pulse length, if the waveform is CW. Note that in this case T can limit the minimum range you can detect. Or you can use c/(2B) where B is the bandwidth of the signal as you stated. I believe the limit is wavelength/2 for resolution though.

Yup. And in order to get a pulse of T you need, at best, a sinc window. Resolution is intrinsically linked to bandwidth.
