%X Using the C-band ERS-1/2 images of Shanghai,which were collected in 1996 and 1998 respectively,the three pass differential interferometry is carried out.The deformation for about two years at Lujiazui region of Shanghai is detected and the effects on DInSAR are also analyzed.The experiment shows that the urban deformation can be effectively detected by differential interferometry,but the effective methods will needed to eliminate or decrease the effect of atmospheric delay because urban constructions will result in de-correlation and atmospheric delay mainly affects the surveying accuracy.
