摘要
随着InSAR技术的不断成熟和SAR数据获取能力不断提高,InSAR技术逐渐成为高效的地面沉降监测技术。基于InSAR技术的地面沉降监测应用逐年增多,但多为局部小区域应用。本文从InSAR技术选择、SAR数据选用、沉降成果修正与拼接等方面介绍了大区域地面沉降监测中的关键技术方法,并以山东省鲁西、鲁北地区近10万km^(2)区域为例,开展了大区域地面沉降监测实践应用。
With the continuous maturity of InSAR technology and the continuous improvement of SAR data acquisition capabilities, InSAR technology has gradually become the most efficient ground subsidence monitoring technology. The application of ground subsidence monitoring with InSAR is increasing year by year, but most of them are small area monitoring applications. The key technical methods in large-area ground subsidence monitoring were described, such as InSAR technology selection, SAR data selection, and ground subsidence results correction and splicing. Those methods are used to obtain the ground subsidence information of the western and northern regions of Shandong province, where is nearly 100 000 square kilometers.
