摘要
利用欧空局ENVISAT ASAR雷达数据,获取了SAR影像的干涉条纹并结合SRTM DEM数据,分别采用了二路差分和三路差分对武安市下团城村铁矿区域地表沉降进行监测,获得了区域内的最大沉降值和沉降带分布情况,初步探索了无目标、无时域、大范围、高精度地对地表进行沉降监测的方法,得出了影响最终结果精度的主要因素。
The interferenee stripes of SAR image was obtained by using radar data of the European Space Agency EN-VISAT ASAR. Through monitoring land subsidence in Xiatuancheng lron Mine in Wu＇an city by means of two-pass and three-pass differential interferometry, thc 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 ＆,main was preliminarily explored. Then the main factors of affecting the accuracy of final results were got.
