SIR-B stereo-radargrammetry of Australia

Abstract We report on further results of an ongoing programme of radargram-metric experimentation with Space Shuttle Imaging Radar (SIR-B) data. Six Stereo models of orbits over Australia were processed in an analytical stereo plotter. Height accuracies were up to ± 25 m or 1·8 times the range resolution. This is better than in previous SIR-B stereo work, probably due to better image quality. Some inconsistencies were encountered between look angle geometries and height measurement accuracies. While general observations about earlier SIR-B stereo results were confirmed, inconsistencies with theoretical expectations could not be fully explained.
