Abstract

In many geophysical problems, we are presented with a large amount of data and asked to invert for some set of physical parameters, the focus being on the design and solution of the inverse problem; in radargrammetry, however, the inverse problem is straightforward and we must concern ourselves instead with picking the useful data attributes to invert. This paper discusses Synthetic Aperture Radar (SAR) imaging with emphasis on radar backscatter properties. In studying how planetary surfaces modulate the radar cross-section, we determine that both the amount of and variation in backscattered microwave energy provide the necessary cues (i.e., object shading and boundary information) for stereo-interpretation. While past research into automated reconstruction of topography from radar stereo-pairs has concentrated on the use of shading, we show that boundary information may also be used successfully. We also identify how these attributes can be potentially misleading. In closing, this work suggests a process for generating high-quality topography maps from Salt imagery.
