Development of a Ground-based Synthetic Aperture Radar System for Highly Repeatable Measurements

We introduce the development of a robust ground-based synthetic aperture radar (GB-SAR) system capable of obtaining highly accurate SAR images of surface targets repeatedly by dedicated efforts for accurate motion control and innovative system design for stable RF acquisition. A brief introduction of the GB-SAR system and some test images will be followed by the accuracy assessment of the system performance for the future radar-interferometric applications to natural or anthropogenic surface/sub-surface targets.
