The Project
Multi-Temporal Synthetic Aperture Radar (SAR) Interferometry (MT-InSAR)
The capability of SAR interferometry to remotely monitor areas much wider than traditional surveying techniques, without the necessity to install in-situ ground instrumentation, makes this technique particularly suitable both for historical sites characterization and single building monitoring. MT-InSAR cannot be used as a real-time monitoring tool due to the current revisiting times of the satellites. However, considering the growing investments of the national and international community, it is reasonable to assume that in the near future there will be systems offering daily acquisitions.
In this proposal the following multitemporal SAR interferometric techniques for the detection of structural and ground motions affecting the archaeological heritage and monuments:
a) Persistent Scatterers Interferometry (PSI) approach based on the GAMMA/ Interferometric Point Target Analysis (IPTA) processing scheme customized for monument scale monitoring.
b) A heritage-monitoring-oriented Tomography-based Persistent Scatterers Interferometry (Tomo-PSInSAR). This technique integrates merits from PSInSAR and SAR tomography.
