【摘要】 利用某高速采空区的ALOS卫星6景PALSAR数据,采用二轨差分干涉处理的数学模型,在完成图像的配准、重采样、去除地形相位、滤波和相位解缠之后,获取了高速公路采空区D-InSAR条带变形时间序列,并与实测数据进行了比较,将InSAR数据进行改正,结果显示D-InSAR用于公路采空区变形监测是可行的,具有广泛的应用前景。更多还原

【Abstract】 This paper uses the ALOS satellite 6 scene PALSAR as experimental data.Using the mathematical model processed by two-track differential interferometric,after completing image registration,resample,removing terrain phase,filtering and phase unwrapping,the D-InSAR strip deformation time series of highway goaf are achieved.Comparing the test data with measured data and correcting InSAR data,the results show that it is feasible to use the D-InSAR to monitoring highway deformation above goaf,which has broad application prospects.更多还原
