Shuttle Imaging Radar-B, the second in a series of NASA Earth-imaging instruments employing radar technology, was designed to fly aboard NASA's Space Shuttle Challenger, STS-41-G, to collect radar images of Earth at several angles.
The multiangle images, an improvement on the single angle images collected by the instrument's predecessor, allowed scientists to create perspective views of the landscape.
