EUSAR 2021 Welcome Message of the Technical Chairman

It’s a great pleasure to welcome you to the At the closing session on the last day of the confer- 13th European Conference on Synthetic Aperture ence a Best Paper Award, a Best Poster Award, and Radar (EUSAR) 2021 which will be the first virtual three Best Students Awards will be presented. The ­digital edition in this series. independent award committee is under the lead of Prof. Lombardo from Sapienza University of Rome. As in the previous years, this EUSAR enjoys a superior response from academia, industry and All papers received prior the deadline and presented scientific institutions from all over the world. To our at the EUSAR conference will profit from the visibility greatest pleasure, all important fields of SAR have of their contributions in ISI and SCOPUS databases, been covered, including the latest results from SAR whereas the publications will be made accessible in systems and missions, news from the cutting-edge the conference proceedings and in IEEEXplore. in technology and signal processing, and advanced data evaluation, modelling and feature extraction, as I would like to express my thanks to all authors for well as unconventional applications, and not to forget their outstanding submissions and their patience interesting ideas for new upcoming projects. during these days.

20 Years after SRTM Gerhard Thiele Rheinisch-Westfälische Hochschule (RWTH) in Aachen

Born on 2 September 1953 in Heidenheim, Germany. Studied Physics at University in München and Hei- delberg, where he received his Ph.D. at the Institute for Environmental Physics in 1985. He performed post- doc research at Princeton University before joining the German astronaut corps in late 1987. In 1996 Thiele moved to Houston, Texas, where he was trained as mission specialist by NASA. In February 2000 he participated in the STS-99 Shuttle Radar Topography Mission, which aimed at generating a 3D digital topographical map of Earth’s landmass. In 2001 Thiele returned to the European Astronaut Centre in Cologne, where he became head of the astronaut division in 2005. In 2009 Thiele was responsible for the last ESA astronaut selection. Since 2010 Thiele worked as resident fellow at the European Space Policy Institute in Vienna focusing in his research on Space Exploration and on European Autonomy in Space. In 2013 he became Head of the Strategic Planning and Outreach Office in the Directorate of Human Spaceflight and Operations at ESA. Since 2016 Thiele is self-employed and has a lecturer assignment at the Rheinisch-Westfälische Hoch- schule (RWTH) in Aachen. Gerhard Thiele is married and has four children.

10:20 – 10:50 Keynote II (Track A)

Tomographic techniques in x-ray imaging Martin Fiebich Technische Hochschule Mittelhessen, Germany

Professor Dr. Martin Fiebich studied physics at the Universität of Münster from 1982 to 1988. As a gradu- ate physicist, he then worked at the Institute for Clinical Radiology at Münster University Hospital and was employed there as a medical physicist from 1988 to 2000. During this time, he completed supplementary studies in medicine and completed his doctorate in medicine in 1995. From 1996 to 1998, he worked in the Department of Radiology at the University of Chicago in the Kurt Rossmann Laboratories on research in computer-assisted diagnosis. In 2000, he received an appointment at the Technical University of Central Hesse in the field of imaging systems in medicine. He has been a member of Working Committee AA6 “Imaging Techniques” of the German Stadardization Group in Radiology (NAR) since 2005 and is chairman of this committee since 2010. In 2011, he was appointed to working committees of the German Commission on Radiological Protection, e.g., working committee A2 “Medicine” and A4 “Radiation Protection Technology” as well as the working group “Measurement Uncertainties” and he was head of the working group “Quality Assurance in Medicine” from 2017 to 2018. From 2014 to 2020, he was chairman of the “Biomedical Imaging” division of the German Society for Medi- cal Physics (DGMP) and is currently vice president of the DGMP since 2021. Professor Fiebich’s research focuses on dose optimization for patients and staff, the development of new methods in quality assurance, and dosimetry in X-ray diagnostics especially in computed tomography.
