摘要
作为InSAR系列讲座的最后一篇,本文以台湾西部作为典型的实验区,基于InSAR技术,使用欧洲空间局卫星ERS-1/2所获取的多幅SAR影像进行地表三维重建和地震同震形变探测,并与GPS观测数据对比,分析干涉结果的精度。最后分析InSAR的应用局限性,并指出潜在的解决途径。
As the last part of the tutorial, the paper shows the experimental results derived with satellite InSAR over the typical testing site, the west of Taiwan. The experiments are conducted for both the three-dimension （3D） reconstruction and the co-seismic deformation detecting by using the multiple SAR images collected by the satellites, ERS-1/2, operated by European Space Agency. The accuracies of the interferometric results are evaluated by comparing with the GPS data. The emphasis is finally placed onto the discussion of InSAR limitations, and the potential approach overcoming the problems is also pointed out.
