| Abstract: | By using 38 ENVISAT ASAR images between 2003-10—2009-06 of TianJin area, we conduct the differential interferometry and PS pixel selection experiment, and then extract the subsidence of experimental area. According to the time and space characteristics, using space and time filter to separate the atmospheric delay, orbit error,DEM residual phase,we obtained average settlement rate of test site, and finally selected PS pixels in four typical regional mapped the time sequence settlement diagram. |
| Keywords: | ground subsidence differential interferometry decorrelation atmosphere delay persistent scatterer |
