中文摘要：

地基SAR（Ground Based Synthetic Aperture Radar,GB-SAR）是进行区域性、全天时、全天候、定点连续形变监测的重要手段。该文对中国科学院电子学研究所研制的地基SAR系统ASTRO（Advanced Scannable Two-dimensional Rail Observation system）的形变监测性能进行分析,结合ASTRO系统成像几何给出了其形变监测模型和精度分析模型,着重分析了影响形变监测精度的主要误差源。最后以ASTRO系统为实验平台开展了形变监测实验与分析,验证了ASTRO系统用于形变监测的能力。

英文摘要：

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.
