Short Range SAR Imaging for 2D Micro-Deformation Detection

With the development of modern remote sensing techniques, high stability and super-resolution detection abilities are required to obtain an excellent performance in micro-deformation monitoring regions, such as civil architectures monitoring, disaster alarming and environment monitoring. A portable synthetic aperture radar (SAR) system based on interference technique and phase inversing technique is proposed and utilized for 2-D micro-deformation monitoring in this paper. Experiments are constructed to verify that the system can preciously and accurately get the micro-deformation in range direction and azimuth directions.
