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。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 unwrap- ping, the D - InSAR strip deformation time series of highway goaf are achieved. Comparing the test data with measured data and cor- recting 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.
