Development of a Simple Ground-Based Synthetic Aperture Radar System for Monitoring Fault Creep

Ground-based synthetic aperture radar (GB-SAR)is known as a powerful tool for monitoring ground displacement. Fault creep is important to understand diastrophism. Particularly, Marikina fault in Manila, Philippine is known as a place where fault creep has often occurred. In this paper, we demonstrate a prototype GB-SAR, which we developed, which is suitable for environmental monitoring. As a first step, we developed a GB-SAR with a simple structure, which uses a frequency not limited by a location by law. We conducted some experiments for generating SAR images by the developed GB-SAR. In the experiments, we showed we could image several targets under various conditions by SARs.
