The German aerospace center, DLR, now has the twin synthetic aperture radar spacecraft TerraSar-X and Tandem-X operating in formation.With that capability in hand, the radar satellites now can take stereo images of points on the ground to deliver enhanced accuracy.Here is a DLR-released picture of Mt. Etna, the Sicilian volcano, derived using that bistatic technique:The two satellites took the image of Mt. Etna at the same time to be able to build a three-dimensional picture. The satellites were within 350 meters of each other.The derived picture has a height accuracy down to 2 meters. The bistatic imaging technique is deriving much greater performance than was achieved with the Shuttle Radar Topography Mission, DLR says.
