Abstract: | Side-looking spacecraft radar imagery has thus far been produced only from an orbit around the Moon. This was a part of the Apollo Lunar Sounder Experiment (ALSE) of the Apollo 17 mission in December, 1972. This paper reports results of a radargrammetric evaluation of overlapping Apollo 17 synthetic aperture radar images (wavelength 2 m). The potential to map from single images and to reconstruct 3D stereoscopic models is studied. The relative height accuracy achieved is about ± 100 m and is thus competitive with that obtained with the vidicon camera that is presently used for planetary exploration.NAS-NRC Resident Research Associate. |
