We've done work with some commercial customers researching low-power
active radar with USRPs, but these were (customer) internal projects
that did not get published externally.

Regarding passive radar--it is very difficult with low-cost hardware
such as the USRP to get the dynamic range needed to simultaneously
receive the direct path from an emitter and the echoes from an
airborne target.  Some types of scene geometry would allow physical
shielding to attenuate the direct path for a subset of the antenna
array, which would help reduce the dynamic range necessary.
