Abstract:
Shortly after the big hype the new multiple-input-multiple-output (MIMO) technology caused in wireless communication research, "MIMO" became a hot topic in the radar community as well. In this presentation first the basic idea of MIMO is explained and a definition is given to distinguish the different technologies often mixed in this context. In a second part a quasi MIMO system based on FMCW is presented where the transmit signals are radiated sequentially.
Measurement results demonstrate the use of a MIMO radar in a traffic application. The third part of the presentation is dedicated to a new concept for MIMO radars based on OFDM which allows simultaneous transmission of all signals while providing a superior separability.
Initial results are shown to demonstrate the future capabilities of the MIMO technology.

Curriculum Vitae: Thomas Zwick (S’95–M’00–SM’06) received the Dipl.-Ing. (M.S.E.E.) and the Dr.-Ing. (Ph.D.E.E.) degrees from the Universität Karlsruhe (TH), Germany, in 1994 and 1999, respectively. From 1994 to 2001 he was a research assistant at the Institut für Höchstfrequenztechnik und Elektronik (IHE) at the Universität Karlsruhe (TH), Germany. In February 2001 he joined IBM as research staff member at the IBM T. J. Watson Research Center, Yorktown Heights, NY, USA. From October 2004 to September 2007, Thomas Zwick was with Siemens AG, Lindau, Germany. During this period he managed the RF development team for automotive radars. In October 2007, he became a full professor at the Karlsruhe Institute of Technology (KIT), Germany. He is the director of the Institute of Radio Frequency Engineering and Electronics (IHE) at the KIT. He is author or co-author of over 200 technical papers and 20 patents. His research topics include wave propagation, stochastic channel modeling, channel measurement techniques, material measurements, microwave techniques, millimeter wave antenna design, wireless communication and radar system design. Thomas Zwick received over 10 best paper awards on international conferences. He served on the technical program committees (TPC) of several scientific conferences. In 2013 Dr. Zwick was general chair of the international Workshop on Antenna Technology (iWAT 2013). He also was TPC chair of the European Microwave Conference (EuMC) 2013 and general chair of the IEEE conference on Microwaves in Intelligent Mobility (ICMIM) in 2015. Since 2008 he has been president of the Institute for Microwaves and Antennas (IMA). T. Zwick became selected as a distinguished microwave lecturer for the 2013 – 2015 period with his lecture on “QFN Based Packaging Concepts for Millimeter-Wave Transceivers”. |
