PS技术及其在地表形变监测中的应用现状与发展

doi:10.11867/j.issn.1001-8166.2006.11.1193

合成孔径雷达干涉测量技术（InSAR）为地表形变监测提供了极具应用潜力的手段，具有大面积、高空间分辨率、全天候及成本低的优点。但由于大气条件变化、地表覆被等时间空间去相干的影响，其精度和普适性受到极大限制。近几年发展的永久散射体（PS）技术在传统差分干涉测量（DInSAR）中引入时间维，分析长时间内保持稳定的像元集相位变化，获得毫米级的地表形变测量精度，同时有效地解决了时间空间去相关和大气非均质性影响的问题，目前在滑坡、地面沉降和地质灾害监测等领域得到了广泛的应用。PS技术具有高精度、高时间分辨率、能极大提高影像利用率的优点；但只适用较小区域、需要大量影像、且不适于分析快速突变的地表形变。为克服PS应用中的问题，近年来出现了三角反射体技术、多平台PS技术及相关性像元分析（CPT）技术，使PS技术应用具有更广泛的适应性。

The SAR Interferometry technique is an effective method for monitoring ground deformation and has been used widely. First of all, it has some advantages compared with the conventional approaches, such as covering large area, high spatial resolution and low cost. However, its accuracy and robust are reduced for atmosphere and land cover conditions. In recent years, the Permanent Scatterers technique has been developed, which can reduce the spatial and temporal decorrelation by using a time series of SAR images. At present, it has been used in monitoring landslide, subsidence and geological disaster widely. PS technique has more accuracy, higher temporal resolution and utilization efficiency compared with traditional DInSAR. However，with this technique some limitations should be noticed. For example, only small areas (less than 5 km×5 km large) could be processed, where there were too many images and only slow surface deformation phenomena could be detected. In recent years, some new approaches have been presented such as using corner reflectors, multi-plat PS technique and coherent pixel technique for improving PS technique. 
