Paper Abstract

Calibration of Synthetic Aperture Radar (SAR) data is essential it is to be used in quantitative studies of the Earth's surface. At the Jet Propulsion Laboratory, we have developed a number of approaches for calibrating SAR image data, including data from multi-polarization and multi-frequency systems. This has resulted in an archive of calibrated data at JPL from several different types of scene. In this paper, it will be shown how calibrated SAR data can be used to improve our understanding of some physical properties of the Earth's surface layer. We will show how calibration uncertainties and the presence of system noise should be handled by the SAR data user. Using examples of calibrated SAR data from the NASA/JPL DC-8 SAR, it will be demonstrated how calibrated data can be used to monitor temporal change and to improve the classification of land cover type.
