摘要
东南极格罗夫山地区是由我国科学家最新发现的南极内陆冰盖陨石富集地。本文采用该地区1996年三个时相的JERS-1合成孔径雷达(SAR)原始数据,进行了成像和干涉处理;分析了该地区的雷达图像特征,干涉条纹图与冰面地形、干涉基线(时相、空间)和冰川流动的关系,干涉相干性与基线和冰面变化的关系;定性地揭示了格罗夫山地区冰流的模式,发现了存在于角峰群内部的冰流。此外,本文还分析了该地区干涉去相干的主导因素。
Antarctic Grove Mountain is a newly found Antarctic inland meteorites trap by Chinese scientists. In this article, three JERS-1 SAR L0 scenes are used to SAR processing and interferometric measurement for studying the ice sheet. The characteristics of SAR image and interferogram are analyzed and combined with glacial topography, interferometric baseline and ice flow. The possible sources of INSAR decorrelation are analyzed and the dominant ones are given. Complicated ice flow patterns in Grove are declared qualitatively and two ice flow systems among the nunataks are disclosed.
