09:00-11:00 Bistatic and Multistatic SAR F. Lopez-Dekker (DLR)
Content: The first part of this tutorial will focus on multistatic SAR systems, and possible applications. Specific topics covered include: - Analysis of close-formation configurations, in particular in the context of single-pass interferometric missions. - The impact of oscillator phase errors and an analysis of synchronization options. - Performance analysis, including noise-like errors (discovering the benefits of having large baselines) and, in particular, systematic errors. - Mission-concept examples.
Biography: Paco López-Dekker was born in Nijmegen, The Netherlands, in 1972. He received the Ingeniero degree in telecommunication engineering from the Universitat Politècnica de Catalunya (UPC), Barcelona, Spain, in 1997, the M.S. degree in electrical and computer engineering from the University of California, Irvine, CA, USA, in 1998, under the Balsells Fellowships, and the Ph.D. degree from the University of Massachusetts, Amherst, MA, USA, in 2003, for his research on clear-air imaging radarsystems to study the atmospheric boundary layer. From 1999 to 2003, he was with the Microwave Remote Sensing Laboratory, University of Massachusetts. During 2003, he was a Research Scientist with Starlab, where he focused on the development of GNSS-R sensors. From 2004 to 2006, he was a Visiting Professor with the Department of Telecommunications and Systems Engineering, Universitat Autònoma de Barcelona, Spain. In March 2006, he joined the Remote Sensing Laboratory, UPC, where he conducted research on bistatic synthetic aperture radar (SAR) under a five-year Ramon y Cajal Grant. At the university, he taught courses on signals and systems, signal processing, communications systems and radiation, and guided waves. Since November 2009, he has lead the SAR Missions Group at the Microwaves and Radar Institute, German Aerospace Center (DLR), Wessling, Germany. His current research focuses on the study of future SAR missions and novel mission concepts

13:45-14:30 Digital Beamforming Concepts M. Younis (DLR)
Content: The Digital Beamforming (DBF) SAR referes to synthetic aperture radar systems that utilize multiple receive channels in azimuth and/or elevation. SAR systems utilizing DBF can overcome the fundamental limitations of "conventional" SAR formulated through the minimum antenna area constraint. It becomes possible to operate the system in modes which provide simultaneous wide swath and high azimuth resolution. Basically DBF extends the trade space of SAR systems. However, while the multi-channel architecture offers various possibilities, it is necessary to adapt the operation mode, i.e. the way the hardware is operated, to yield the required performance. In the most general case this involves time varying beams both in azimuth and elevation. Understanding the operation mode is crucial in order to take advantage of the DBF capabilities.
Biography: Marwan Younis received his B.Sc in electrical engineering from the University of Baghdad, Iraq in 1992 and the Dipl.-Ing. and Dr.-Ing. degrees in electrical engineering from the Universität Karlsruhe (TH), Germany, in 1997 and 2004, respectively. From 1998 to 2004, he was a research scientist with the Institut für Höchstfrequenztechnik und Elektronik, Universität Karlsruhe (TH). Since 2005 he has been with the Microwaves and Radar Institute of the German Aerospace Center (DLR), Oberpfaffenhofen, Germany. His research fields include synthetic aperture radar (SAR) systems, MIMO SAR, digital beamforming, SAR performance and calibration, synchronization of bistatic SAR, and antennas. In 2013 he spent a research sabbatical at NASA/JPL. He is associate editor for the IEEE geoscience and remote sensing letter. He is a lecturer with the Universität Karlsruhe (TH) and the Carl-Cranz-Gesellschaft. He received the Hermann-Billing award for his Ph.D. thesis in 2005.

14:45-16:45 Basics of GMTI and Applications with SAR P. Lombardo (Uni Roma)
Content: The Ground Moving Target Indication (GMTI) capability has always been a major requirement for air- and space-borne surveillance radar. Recently, it has also become an important feature for both air- and space-borne SAR, where it requires the use of advanced signal processing techniques. Using SAR the aim is not only at detecting the moving targets, but also at estimating their motion and at appropriately focusing them.
The presentation addresses the basics of radar GMTI with specific emphasis to the peculiarities of SAR GMTI. Specific attention is devoted to moving targets autofocusing from air- and space-borne platforms. The potentialities of multi-channel vs. single-channel SAR are compared, showing interesting but different potentialities. Discussion of GMTI with monostatic, bistatic and MIMO GMTI SAR are introduced, with their processing techniques.
Biography: Dr. Pierfrancesco Lombardo graduated in July 1991 at the University of Rome "La Sapienza", Italy. After serving at the Official Test Center of the Italian Air Force, he was associate at Birmingham University (UK) and at Defense Research Agency in Malvern. He received his Ph.D in November 1995 and in 1996 was research associate at Syracuse University (NY-USA). In 1996 he joined the University of Rome “La Sapienza”, where he is presently Full Professor.
Dr. Lombardo is associate Editor for Radar Systems for the IEEE Transactions on Aerospace and Electronic Systems (AES) since June 2001. He is co-recipient of the best paper award, entitled to Mr. B. Carlton, of IEEE Trans. on AES for the year 2001 and of the best paper award for the IEEE Trans. on Geoscience and Remote Sensing for the year 2003. He is member of IEEE AES Radar System Panel, and the Editorial board of IET Proceedings on Radar Sonar and Navigation.
Dr. Lombardo’s research has been reported in over 220 publications in international technical journals and conferences. He served in the technical committee of many international conferences on radar systems and signal processing. He was Chairman of Technical Committee of the IEEE/ISPRS Joint Workshop on Remote Sensing and Data Fusion over Urban Areas URBAN’2001, Rome, Italy, URBAN’2003, Berlin, Germany, and URBAN’2005, Tempe, Arizona (US). He was also co-Chairman of the IEEE Radar Conference 2008.
