| 摘 要： | 研究了使用ENVISAT(European environmental satellite)ASAR (advanced synthetic aperture radar) 数据进行重复轨道干涉测量时, 如何利用MERIS ( mediumresdution imaging spectrometer)水汽产品去除干涉差分图中的水汽效应。通过理论研究, 建立了大气校正模型, 并以长江中下游地区宜都市的差分干涉测量为例, 对其进行大气校正。试验结果表明: 斜距向形变的方差显著减小, 干涉测量精度得到了有效改进, 综合应用ASAR 和MERIS 数据可以有效地去除重复轨道InSAR(interferometric synthetic aperture radar)中的大气效应。

| Abstract: | The purpose is to discuss how to correct the atmospheric effects on repeat-pass InSAR. A specific way integrated with MERIS and ASAR was put forward with its elaborate characters and theory. Taking a differential interferogram with test site located in Yangtze River side as a sample, this specific correcting model was applied and tested. Results show that the RMS of deformation in the range direction is obviously decreased and the precision of measurement is enhanced greatly. |
