摘要(Abstract)：

针对传统地质灾害隐患排查手段无法进行全天时、全天候、大范围识别监测的问题，该文以ALOS-2升轨和Sentinel-1A升降轨雷达影像为数据源，利用时序InSAR技术开展了贵州省六盘水和黔西南区域地质灾害隐患识别监测，同时基于SAR卫星入射观测方向和地形地貌之间的关系，对研究区域侧视成像几何可视性进行判别分析。最后综合利用3种数据获取的形变结果以及结合光学影像、地形等数据进行了形变解译，共识别出108个地质灾害疑似隐患点，并通过外业核查验证了地质灾害隐患识别的准确性。实验结果表明，时序InSAR技术能够有效进行地质灾害隐患识别监测，可为地质灾害防治提供科学依据。
