Deformation Detection Error Analysis and Experiment Using Ground Based SAR


Abstract:
Ground Based Synthetic Aperture Radar (GB-SAR) is an effective tool for regional deformation detection, it has the ability of continuous monitoring for a certain area day and night regardless of the weather condition. ASTRO (Advanced Scannable Two-dimensional Rail Observation system) is a GB-SAR system constructed by Institute of Electronics Chinese Academy of Sciences (IECAS). In order to make out the deformation detection performance of ASTRO, GB-SAR imaging geometry is presented, the deformation detection model and the analysis of error sources are derived in this paper. The deformation detection error sources are analyzed using precise deformation geometry. Finally, a deformation detection experiment is carried out using ASTRO, and the results demonstrate the ability of deformation detection.
