2019年京津冀平原区1:200万Radarasat-2雷达卫星地面沉降监测数据

为了实现统一时段、完整覆盖京津冀平原区地面沉降年度动态监测，中国自然资源航空物探遥感中心以Radarasat-2雷达卫星为主要数据源，按照Radarsat-2雷达卫星数据的覆盖特点，选择平行轨道下获取的同一入射角的扫描数据，采用相干目标InSAR时序分析的多轨道、长条带形变信息提取技术方法，获取了京津冀平原区2017年度地面沉降的空间分布特征。

To conduct annual dynamic monitoring of land subsidence over the Beijing-Tianjin-Hebei Plain with a unified time frame and full coverage, the China Aero Geophysical Survey and Remote Sensing Center for Natural Resources took Radarsat-2 radar satellites as the primary data source. Based on the coverage characteristics of Radarsat-2 data, scanning data acquired under parallel orbits with identical incidence angles were selected. By applying the multi-orbit and long-strip deformation information extraction technology based on coherent target InSAR time-series analysis, the spatial distribution characteristics of land subsidence in the Beijing-Tianjin-Hebei Plain in 2017 were obtained.
