Umbra Synthetic Aperture Radar (SAR) Open Data

Umbra satellites generate the highest resolution Synthetic Aperture Radar (SAR) imagery ever offered from space, up to 16-cm resolution. SAR can capture images at night, through cloud cover, smoke and rain. SAR is unique in its abilities to monitor changes. The Open Data Program (ODP) features over twenty diverse time-series locations that are updated frequently, allowing users to experiment with SAR's capabilities. We offer single-looked spotlight mode in either 16cm, 25cm, 35cm, 50cm, or 1m resolution, and multi-looked spotlight mode. The ODP also features an assorted collection of over ...

安姆布拉卫星（Umbra）所获取的合成孔径雷达（Synthetic Aperture Radar, SAR）影像，拥有目前太空平台提供的最高分辨率，最高可达16厘米。合成孔径雷达可在夜间、穿透云层、烟雾与降雨等条件下获取影像，其在地表变化监测领域具备独特的技术优势。本次开放数据计划（Open Data Program, ODP）涵盖二十余个多样化的时序监测点位，且更新频率较高，可为用户提供合成孔径雷达性能测试的实践场景。本项目提供单视聚束模式（分辨率可选16cm、25cm、35cm、50cm或1m）以及多视聚束模式。此外，开放数据计划还收录了一套丰富的逾...
