COSMO-SkyMed是意大利航天局和意大利国防部共同研发的高分辨率雷达卫星星座，2010年11月完成了全部4颗X波段合成孔径雷达（SAR）卫星的发射。它是全球第一个由4颗卫星组成的分辨率最高达1米的雷达卫星星座，具有雷达干涉测量能力，具备全天候、全天时对地观测能力，卫星星座特有的短重访周期等优势，能够弥补光学影像在时间和空间上的局限，目前已广泛应用于测绘、国土、城市规划、海事管理、地质勘测、灾害管理、农林渔牧、环境保护等领域。\n
\n2012年共获取COSMO-SkyMed影像3景。覆盖范围均为中游人工绿洲生态水文试验区，获取时间（北京时间）分别为：2012-07-25 07:12，2012-07-28 19:55，2012-08-02 07:12。\n
\n获取的3景数据均为PingPong模式，分辨率15 m，产品级别为SLC，极化方式为VV/VH, HH/HV和VV/VH。
