Monitoring bridges and tunnels is crucial to ensure transportation safety. MT-InSAR techniques have proven highly effective for remote infrastructure monitoring, enabling operators to identify risk areas and make informed decisions on detailed structural interventions.

The objective of ARTEMON-BT is to develop a methodological workflow based on MT-InSAR techniques for multi-temporal monitoring of bridges and tunnels, allowing the extraction of kinematic parameters such as displacement velocities and accelerations from PS/DS time series. These parameters support targeted inspections and help prevent structural failures, while also addressing issues related to the sensitivity of interferometric measurements, the use of artificial reflectors, and comparison with EGMS Sentinel-1 data to improve analysis accuracy.

Starting from medium-resolution Sentinel-1 satellite data, the level of detail will be enhanced using high-resolution COSMO-SkyMed data, supported by the deployment of artificial reflectors where necessary, in order to improve coverage and evaluate solutions capable of ensuring multi-mission visibility and multiple acquisition geometries.

The highest level of methodological detail includes guidance for potential UAV-based analyses to closely examine critical infrastructure components identified through satellite monitoring, as well as optimizing the placement of artificial reflectors based on topography and land use.
