  • 摘要: 城市地表和人工建筑的稳定性监测一直是城市安全的重要监测内容之一。星载合成孔径雷达干涉测量(InSAR)技术以其大范围、高精度、高空间密度的形变获取能力,被广泛用于大范围地表形变监测。近年来,随着星载SAR系统分辨率的不断提高,时序InSAR技术越来越多地应用于重要基础设施的监测。该文结合作者团队长期基于时序InSAR技术在城市地区监测研究经历,总结和回顾了团队关于时序InSAR方法在城市动态监测中的一些典型应用,包括城市机场、高架路网、桥梁、铁路和地铁沿线等,根据多年获取的高分辨率TerraSAR-X影像、Cosmo-SkyMed影像以及后续免费获取的Sentinel-1影像等多种数据以及监测研究中发现的研究问题及相应解决方法,在应用中取得了良好的效果,展现了时序InSAR技术在城区目标精细监测中的潜力。
