Antarctic Grove Mountain is a newly found Antarctic inland meteorites trap by Chinese scientists. In this article, three JERS-1 SAR ID scenes are used to SAR processing and interfero-metric measurement for studying the ice sheet. The characteristics of SAR image and interfero-gram 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 a-mong the nunataks are disclosed.
