Abstract: 为了解决合成孔径雷达干涉测量(InSAR)不能真实反映三维地表形变量,给分析地震的水平位移场和垂直位移场带来困难的问题,提出一种联合利用GPS和InSAR观测结果计算地表三维位移的方法,并以汶川地震为例进行计算。计算结果表明,汶川地震具有明显的右旋和逆冲特征。
InSAR(Synthetic Aperture Radar Interferometry)can only obtain the displacements along direction of LOS(line-of-sight),it is not the real three-dimensional surface deformation.Therefore it is difficult to analyze both vertical and horizontal terrain displacements.A method combining GPS and InSAR data to calculate three-dimensional terrain displacements of Wenchuan earthquake is proposed.The results show that the earthquake pupture is obviously right-leteral and thrust.
