摘要： 作为欧空局地球探测计划的第一个机会任务，CryoSat-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。CryoSat-2任务的优势在于高精度地测量地球陆地和海洋冰原的变化，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CryoSat-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CryoSat-2的首要载荷SIRAL和数据校准，最后探讨了CryoSat-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.
