| Abstract: | The interference stripes of SAR image was obtained by using radar data of the European Space Agency ENVISAT ASAR. Through monitoring land subsidence in Xiatuancheng Iron Mine in Wu'an city by means of two-pass and three-pass differential interferometry，the maximum subsidence value and the distribution of subsidence zone were determined，with combination of the SRTM DEM data. And the technology of large scale and high accurate land subsidence monitoring without target and time domain was preliminarily explored. Then the main factors of affecting the accuracy of final results were got. |
