摘要 Sentinel-1A是欧空局"哥白尼计划"发射的首颗对地观测卫星,其搭载的C波段SAR传感器有效地延续了ERS-1/2和ENVISAT ASAR对地观测任务。简要介绍了Sentinel-1A卫星的特点和轨道参数,并与ERS-1/2和ENVISAT ASAR进行了对比。详细介绍了Sentinel-1A的成像模式(SM,IW,EW,WV)以及每种模式下数据产品(Level-0,Level-1,Level-2)的特征。最后分析了Sentinel-1A数据在不同领域的实际应用,为其在对地观测中的广泛应用提供了参考。 Sentinel-1A is the first satellite of the ESA Copernicus program with a C-band SAR. It is a continuation of the SAR data stream following the older versions of the same sensor on ERS-1, ERS-2, and ENVISAT. In this paper, we compare the sensor and orbit parameters from the four satellites. The imaging modes of Sentinel-lA, SM, IW, EW, WV, are described, and the corresponding products (Level-0, Level-1 Level-2) are pointed out. Potential applications of the data from each mode are highlighted in order to provide guidance for future studies.
