Sentinel-1A SAR影像及其在矿区地面沉降监测中的应用研究
|
摘要
详细介绍了Sentinel-1A SAR影像数据的基本参数、工作模式、应用领域等。利用2016.11.09—2017.03.09的5景Sentinel-1A C波段SAR影像数据进行矿区地面沉降监测试验。基于SARscape利用双轨D-In SAR技术进行差分干涉处理,得到了研究区地面沉降分布图,直观地再现了研究区在2016.11.09—2017.03.09的沉降分布、沉降量级等。结果表明济宁某矿区在监测期间地面相对稳定,未有大面积和大量级的地面沉降发生,4个干涉对监测到的最大沉降都未超过3 cm。
The basic parameters,working modes and application fields of Sentinel-1A SAR image data are introduced in detail. Then five Sentinel-1A SAR images from November 9,2016 to March 9,2017 are collected and used to form four interferometric pairs to monitor the mining-induced ground subsidence of the study area. The differential interferometric processing is carried out based on SARscape and two-pass D-In SAR to obtain the ground subsidence map of our study area,which intuitively reproduces the subsidence distribution and magnitude of our study area between November 9,2016 and March 9,2017. The results show that the ground of our monitored mine in Jining is relatively stable,there is no large area and magnitude of subsidence and the monitored maximum subsidence of four interferometric pairs is not more than 3 cm.
