| 摘 要： | 作为欧空局地球探测计划的一项重要任务,Cryo Sat-2卫星于2010年携带着Ku波段SIRAL(干涉/合成孔径雷达高度计)发射升空。Cryo Sat-2任务的优势在于高精度地测量两极海冰厚度以及监测南极大陆和格陵兰冰盖的变化,同时92°的近极地轨道一定程度上填补了先前遥测卫星的高纬数据缺口。本文对Cryo Sat-2卫星的科学目标、科学需求、任务概况、仪器载荷以及数据产品等方面做了详细的介绍,重点强调了Cryo Sat-2的首要载荷SIRAL和数据校准,最后探讨了Cryo Sat-2在极地领域的应用。

| Abstract: | Equipped with a Ku-band SIRAL(SAR/Interferometric Radar Altimter), CryoSat-2 has been launched in 2010 as the first European Space Agency Earth Explorer Opportunity mission.CryoSat-2 has the advantage of measuring fluctuations in Earth’s land and marine ice fields with high precision.The low earth, polar orbit at inclination of 92? fills the previous remote sensing satellite data gaps in a certain extent. In this paper, an overview is provided of the CryoSat-2’s scientific objectives, scientific requirement, mission, instrument concept and data products, with an emphasis on the primary load SIRAL and data calibration. Finally the applications of CryoSat-2 in polar region are introduced. |
