| Abstract: | 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. |
