基于哨兵-1A数据的D-InSAR地表沉降监测研究

Research on Surface Subsidence Monitoring of D-InSAR Based by Sentinel -1A Data

本文采用D-InSAR技术对试验区范围内收集的3期哨兵-1A数据进行处理, 获取地表沉降区域.试验结果与采矿区分布位置相吻合, 表明哨兵-1A数据在大范围地表沉降监测中是切实可行的, 能使工作人员全面、 及时、 快速掌握大范围地表形变状况, 有效降低监测成本.

In this paper, the D-InSAR technology was used to process the 3 phase sentinel -1A data collected in the experimental area, and the surface subsidence area was obtained. The results of the experiment coincided with the distribution of the mining area, which showed that the sentinel - 1A data was feasible in the large-scale surface sub- sidence monitoring. It could make the staff fully, promptly and quickly grasp the large scale surface deformation con- dition and effectively reduce the monitoring cost.
