摘要(Abstract)：

针对因IW工作模式数据在南极地区覆盖不全面导致对南极接地线的全面提取造成影响的问题,提出利用双差干涉测量提取接地线的基本原理,分别利用工作模式为IW和EW的Sentinel-1雷达卫星数据,对东南极毛德皇后地沿岸冰川接地线进行提取,将提取结果分别与MEa-SUREs接地线产品进行对比,同时再将这两种模式下的提取结果进行对比分析。结果表明,双差干涉测量可以去除冰流相位的影响,使用EW工作模式的Sentinel-1数据进行南极接地线提取可以忽略其地面分辨率较低这一缺陷,同时,这一模式的Sentinel-1数据在幅宽、南极覆盖范围等方面更具优势。因此,综合利用IW和EW工作模式的Sentinel-1数据,对南极接地线的全面、高效、长期动态监测具有重要意义。
