DESCRIPTION:Monitoring critical infrastructures and structures (energy and 
 transportation) is one of the application domains of national relevance fo
 r which satellite technologies may be exploited to improve detection of ca
 usative factors of deterioration\, mapping of sectors at risk\, and priori
 tization of structural and maintenance works.\nAlthough ground-based non-d
 estructive testing (NDT) methods have been successfully applied for decade
 s\, reaching very high standards for data quality and accuracy\, Synthetic
  Aperture Radar (SAR) satellite technology and interferometric techniques 
 (InSAR) have proved to be a real “game changer”. The impact on infrast
 ructure monitoring was particularly significant\, also in light of the inc
 reased flow of SAR data collected in different radar bands and disseminate
 d by space agencies in these past years.\nASI’s COSMO-SkyMed constellati
 on operating in X-band is among the satellite assets that are mostly explo
 ited by scientific and commercial community to perform high precision and 
 accuracy monitoring\, at high spatial and temporal resolution. Recent stud
 ies undertaken by ASI following “data exploitation” initiatives of COS
 MO-SkyMed data have highlighted an increasing use of these data to study a
 nd monitor bridges\, motorways\, railways\, pipelines and plants. Scientif
 ic proof of concepts and demonstrators have led to strengthening national 
 and international expertise in the use of InSAR multi-temporal techniques\
 , and paved the way for downstream applications and mature monitoring serv
 ices.\nAt the same time\, the global scale availability of C-band Sentinel
 -1 data has contributed to a further dissemination of InSAR techniques for
  infrastructure monitoring\, although the specialist literature has highli
 ghted the limitations due to spatial resolution\, as well as the need to c
 ombine different band SAR data collected at different resolution.\nFrom 20
 21 to 2023\, through the “Multi-mission and Multi-Frequency SAR” Progr
 am (Tapete et al.\, 2022)\, ASI has supported R&D projects focusing on dat
 a fusion and post-processing techniques in the field of infrastructure def
 ormation monitoring. Benefits achievable through integration of multi-band
  SAR data (including L-band SAOCOM) have been demonstrated.\nIn light of t
 hese investments and the maturity of SAR data processing algorithms for ge
 neration of application products\, ASI continues their institutional missi
 on according to the following activities:\n•	In the upstream sector of s
 atellite missions\, improving SAR sensors to achieve new observation capab
 ilities with COSMO-SkyMed Second Generation (CSG) satellites and facilitat
 ing the accessibility to long time series ensuring observation continuity\
 ;\n•	In the downstream sector of applications and services development\,
  promoting SAR data exploitation\, also in combination with navigation and
  telecommunications technologies\, through the new programme “Innovation
  for Downstream Preparation” (I4DP)\, wherein management and monitoring 
 of structural stability of critical infrastructures is among the applicati
 on domains of recent funding and projects initiation.\nThe present paper t
 herefore will illustrate ASI’s contribution on this application domain\,
  alongside the current perspectives\, in light of the COSMO-SkyMed program
 me (upstream) and “Multi-mission and Multi-Frequency SAR” and I4DP pro
 grammes (downstream)\, the latter with particular focus on the initiative 
 dedicated to scientific users (I4DP_SCIENCE).\n\nReferences\nTapete et al.
