Title: Multiplatform Interferometric SAR Approaches for the generation of 3-D ground displacement
Speaker: Antonio Pepe, Italian National Research Council, Italy
Moderator: Florence Tupin
Abstract: In this talk, the general framework used to extract complementary information from multiple sets of interferometric synthetic aperture radar (InSAR) datasets for the reconstruction of the three-dimensional (up-down, east–west, north–south) components of the ground displacement profile will be presented. Specifically, we introduce the basic principles of Burst Overlapped interferometry (BOI) that allows to recover the azimuthal components of the deformation and we present a statistical framework, which also includes the potential use of ground-based (GB-SAR) instruments, to generate 3-D ground displacement time-series and evaluate the quality of the estimates, deriving a variance–covariance matrix of noise sources (i.e., time-inconsistent phase unwrapping mistakes, decorrelation effects, and atmospheric phase screen). The use of conventional and new InSAR products for the effective management of disaster risk chains is also addressed, with examples and an examination of future trends in the development of the InSAR research field.
Speaker's Bio:
Antonio Pepe received the Laurea degree in electronic engineering and the Ph.D. degree in electronic and telecommunication engineering from the University of Naples Federico II, Naples, Italy, in 2000 and 2007, respectively. After graduation, following a short experience at Wind Telecommunication Spa, Naples, in 2001, he joined the Istituto per il Rilevamento Elettromagnetico dell’Ambiente (IREA), Italian National Research Council (CNR), Naples, where he currently holds a permanent position of Research Director. He was a Visiting Scientist with The University of Texas at Austin, Austin, TX, USA, in 2005, Jet Propulsion Laboratory (JPL), Caltech, Pasadena, CA, USA, in 2009 and 2019, and the East China Normal University (ECNU), Shanghai, China, from 2014 to 2019, under the High-End Foreign Experts Recruitment Program of the Chinese State Administration of Foreign Experts Affairs.
From 2012 to 2017, he was an Adjunct Professor of signal theory with the Università della Basilicata, Potenza, Italy. In 2018, he was an Adjunct Professor of wireless telecommunication systems with the University of Naples Federico II. His main research interests include the development of advanced differential synthetic aperture radar interferometry (DInSAR) algorithms for the monitoring of surface deformation phenomena induced by ground subsidence, volcano activities, and earthquakes, with a particular interest toward the phase unwrapping problems. More recently, he has developed research activities for the generation of DInSAR products through multiplatform/multiangle and the new generation SAR instruments, the generation of hybrid scan SAR-to-stripmap DInSAR analyses, the integration of SAR and optical images, and the analysis of land-changes in flooded areas.
Dr. Pepe was a recipient of the 2014 Best Reviewer Mention of the IEEE GEOSCIENCE AND REMOTE SENSING LETTERS and the 2017 Best Reviewer Mention of Remote Sensing (MDPI Journal).
