Alaska Satellite Facility SAR Data Center

The SAR Data Center has a large data archive of Synthetic Aperture Radar (SAR) from a variety of sensors available at no cost. Much of the SAR data in the ASF SDC archive is limited in distribution to the scientific research community and U.S. Government Agencies. In accordance with the Memoranda of Understanding (MOU) between the relevant flight agencies (CSA, ESA, JAXA) and the U.S. State Department, the ASF SDC does not distribute SAR data for commercial use. The research community can access the data (ERS-1, ERS-2, JERS-1, RADARSAT-1, and ALOS PALSAR) via a brief proposal process.

SAR 数据中心拥有来自多种传感器的合成孔径雷达（SAR）的大量数据存档，并提供免费服务。在 ASF SDC 存档中，大量 SAR 数据的分发仅限于科研界和美国政府机构。根据相关飞行机构（加拿大航天局、欧洲航天局、日本宇宙航空研究开发机构）与美国国务院签订的谅解备忘录（MOU），ASF SDC 不得将 SAR 数据用于商业用途。科研界可通过简短的提案程序访问数据（ERS-1、ERS-2、JERS-1、RADARSAT-1 和 ALOS PALSAR）。
