摘要
针对多轨道InSAR数据采集时间异步,在形变区域存在连续运动的情况下,反演结果精度较低的问题。提出基于SBAS-InSAR技术获取矿区地表视线向形变,利用插值数学模型进行时序配准。实际应用中,以乌海矿区为研究区域,选择Cubic算法对研究区域多轨道LOS数据进行时序配准处理,预处理结果与GNSS数据进行对比,结果显示,157轨道插值数据均方根误差小于5 mm,该工作有助于提高矿区三维形变反演结果精度。
The challenge of low inversion accuracy in multi-track InSAR data acquisition arises from asynchronous timing and continuous motion within deformation areas.This paper proposes the application of SBAS-InSAR technology to capture surface line-of-sight deformation in mining regions,alongside the use of interpolation mathematical models for temporal registration.In our practical application,we focus on the Wuhai mining area and employ the Cubic algorithm for temporal registration of the multi-orbit line-of-sight data.The preprocessing results were compared with GNSS data,revealing that the root mean square error for the interpolation data across 157 orbits is less than 5 mm.This work significantly enhances the accuracy of three-dimensional deformation inversion results in mining areas.
