SummaryThe purpose of this research is to develop an advanced synthetic aperture radar tomography-based persistent scatterer interferometry (Tomo-PSInSAR) method to monitor the deformation of Hong Kong’s infrastructure and built environment. The infrastructure and built environmentof a city are major investments. Unfortunately, their maintenance is usually not well coordinated. This may trigger excessive deformation of buildings andinfrastructures (e.g., cracking and spalling of concrete, deflection of walls,settlement of foundations, damage of underground pipelines, etc.). In this research, a superior deformation monitoring method with reliable networks,nonlinear deformation models, robust estimation, GPS correction, and multi-dimensionalsuper-resolution tomography will be developed with special focus on enhancingthe monitoring capability in subtropical complex built environments withcomplicated movements. The deformation patterns and driving forces withreference to typical built environments in Hong Kong (e.g., reclamation,skyscrapers, slopes, etc.) will be revealed. The derived deformation willassist government to carry out maintenance and the revealed deformation patterns will enhance our basic understanding of the dynamics of the builtenvironment and guide future construction.
