OPERA Surface Displacement from Sentinel-1 validated product (Version 1)

The Level-3 OPERA Sentinel-1 Surface Displacement (DISP) product is generated through interferometric time-series analysis of Level-2 Coregistered Sentinel-1 Single Look Complex (CSLC) datasets. Using a hybrid Persistent Scatterer (PS) and Distributed Scatterer (DS) approach, this product quantifies Earth's surface displacement in the radar line-of-sight. The DISP products enable the detection of anthropogenic and natural surface changes, including subsidence, tectonic deformation, and landslides. The OPERA DISP suite comprises complementary datasets derived from Sentinel-1 and NISAR input...三级OPERA哨兵-1（Sentinel-1）地表位移（DISP）产品，通过对二级配准哨兵-1单视复数（CSLC）数据集开展干涉时间序列分析生成。本产品采用混合永久散射体（PS）与分布式散射体（DS）方法，定量反演雷达视线方向上的地球地表位移。DISP产品可用于探测人为与自然地表变化，包括沉降、构造形变与滑坡。OPERA DISP数据集套件包含由哨兵-1与NISAR输入数据衍生得到的互补数据集……
