三轨法DInSAR观测确定区域的垂直变形

Vertical Deformation Determined by Three Pass DInSAR

介绍了三轨法差分合成孔径雷达干涉测量计算区域垂直地壳变形的原理和方法。采用该方法，利用我国可可西里地区的3幅ERS-2卫星SLC（Single Looking Complex）图像对该地区的垂直变形进行了计算研究。结果表明，在1998～2002年期间，研究区最大垂直变形大约为6cm。

The principle and method to determine vertical deformation through 3 pass Differential Interferometry （DInSAS） were discussed in this paper. The vertical deformation was computed by using three Single Looking Complex images in the Kekexili region with software Doris. The results show that the vertical deformation in the region is about 6 cm during 1998-2002.
