is a technique for using two radar
instruments to map a surface, with one emitting and one receiving. The result is a more detailed image than would have been rendered with just one radar instrument. Bistatic imaging can be useful in differentiating between ice
on the surface of the moon
, due to the different ways that radar reflects off these objects—with ice, the radar instruments would detect "volume scattering", and with rock, the more traditional surface scattering would be detected.
