InSAR – showing the way forward

Interferometric Synthetic Aperture Radar (InSAR) is a space-based technology able to measure millimetre-scale displacements of the Earth’s surface and structures thereon. Based on orbiting radar satellites, archives of repeat-pass data are established that facilitate both historical analyses of past motion trends, as well as ongoing monitoring. In recent years InSAR has become a routine tool to complement existing survey technologies in all stages of tunnelling, from design, through construction, to post-construction settlement monitoring. In this presentation, the latest advances in InSAR are shown using examples that illustrate the unique and cost-effective advantages of this technology in each stage of the tunnelling process.
