中文摘要：

大气水汽影响一直是造成重轨星载合成孔径雷达差分干涉测量监测结果不确定性的一个重要因素．本文以地表形变速率稳定的延怀盆地为试验区，利用ASAR数据得到该区域的差分干涉处理结果，利用与ASAR数据获取时间相近的NOAA-16／FY-1C数据对该区域的大气水汽含量进行了反演．通过这些结果，对差分干涉处理结果中大气水汽的影响进行了去除．去除大气水汽影响后得到的地表形变结果与野外考察实测结果基本吻合，从而验证了该方法的可行性。

英文摘要：

Atmospheric water vapour turbulences has results obtained by repeat-pass spaceborne D-INSAR. the interferogram of this area by using ASAR data. At been an important factor which causes confusion in the We select the Yan-Huai basin as a test area and obtain the same time, we make an inversion of the water vapor content by using NOAA-16/FY-1C data obtained at close time with ASAR data. After using these results to remove the water vapour effects, the obtained surface deformation coincides with the field surveying results in general All these results validate the feasibility of this atmospheric correction method.
