| Abstract: | The InSAR coseismic deformation interferogrames derived from ALOS PALSAR data caused by the Wenchuan M_w7.9 earthquake was tested by using GPS measurements. There are constant errors between two sides of the rupture, and bilinear errors of one side of the rupture.It is believed that the constant errors is caused by the phase difference and bilinear errors by the satellite orbit offset error. The InSAR coseismic deformation field calibrated by GPS data are consistent with the forward model inverted from earthquake wave results,the error of calibrated InSAR coseismic deformation is about 5 cm. |
