Prof. Fabio Rocca

Biography: Fabio Rocca, (Dr. Ing. Electronics, 1962) is emeritus Professor of Telecommunications at the Politecnico di Milano and Associate to the Italian Space Agency. Co-founder of two technological companies, Tele-Rilevamento Europa and Aresys, both spin off of Politecnico di Milano.
He invented in 1968 the motion compensation technique, nowadays generally used for video compression. In seismic prospecting for oil, in cooperation with ENI, he studied multichannel filtering, interpolation of faulted surfaces, migration in the frequency domain, bistatic and multistatic processing, blind deconvolution. In Synthetic Aperture Radar he first used seismic migration for focusing, and jointly proposed the use of Permanent Scatterers. He is currently working on the design of bistatic and geosynchronous SAR systems, Polarimetric Tomography, and on airborne radar systems.
    Prof. Rocca is former member (1993?2016) of the Scientific Advisory Groups of the European Space Agency for the radar satellites ERS, Envisat, Sentinel–1, BIOMASS, and currently of the ESA Advisory Committee for Earth Observation, ACEO. In cooperation with LIESMARS, Wuhan University, he participates from 2004 to the Chinese European space research programs Dragon (1 ? 4), sponsored by ESA and by NRSCC.
    Prof. Rocca is Past President of the European Association of Geoscientists and Engineers (1987), honorary Member of the Society of Exploration Geophysicists (1989) and of the EAGE (1998). Italgas Award 1989 and Rhein Foundation 1999 Technology Award for the invention of motion compensation. Doctor Honoris Causa in Geophysics of the Institut Polytechnique de Lorraine, 2001. EAGE Erasmus award for lifetime achievements, 2009.  ENI Prize for New Frontiers for Hydrocarbons (shared with A. Ferretti, CEO of TRE), 2012. Chinese Government International Scientific Technological Cooperation Award, 2013.
    Prof. Rocca coauthored more than 300 publications and participates to 12 patents.

Title:  Phase Calibration of Airborne SAR data for tomographic applications

Synthetic Aperture Radar (SAR) data collected over a two dimensional (2D) synthetic aperture can be processed to focus the data in the 3D space, using   SAR Tomography. A fundamental requirement for this processing is to have precise knowledge of the platform position along the 2D synthetic aperture. This requirement is not easily met in the case of repeat-pass flights. Sub-wavelength platform position errors give rise to residual phase screens among different passes, which hinder coherent focusing in the 3D space. We propose a strategy for calibrating repeat-pass tomographic SAR data in the absence of reference targets, prior information about terrain topography, and even in the absence of any point- or surface-like target within the illuminated scene. The problem is tackled by observing that multiple flight lines provide enough information to jointly estimate platform and target positions. The proposed approach is validated using real data from the ESA campaigns AlpTomoSAR, BioSAR 2008, and TropiSAR. A cross-check of the results from simultaneous P- and L-Band acquisitions from the TropiSAR data-set indicates that the dispersion of the retrieved flight trajectories is limited to a few millimeters.
