Christian Waldschmidt received the Dipl.-Ing. (M.S.E.E.) and the Dr.-Ing. (Ph.D.E.E.) degrees from the University Karlsruhe (TH), Karlsruhe, Germany, in 2001 and 2004, respectively. From 2001 to 2004 he was a Research Assistant at the Institut für Höchstfrequenztechnik and Elektronik (IHE), Universität Karlsruhe (TH), Germany. Since 2004 he has been with Robert Bosch GmbH, in the business units Corporate Research and Chassis Systems. He was heading different research and development teams in high frequency engineering, EMC, and automotive radar. His research topics include integrated radar sensors, radar system design, millimeter wave technologies, antennas and antenna arrays, UWB, and EMC.
In 2013 Christian Waldschmidt returned to academia. He was appointed as Director of the Institute of Microwave Engineering at University Ulm, Germany, as full professor. The research topics focus on radar and rf-sensing, mm-wave and submillimeter-wave engineering, antennas and antenna arrays, MIMO, array signal processing, modulation techniques, and wave propagation.
He authored or coauthored over 80 scientific publications and more than 20 patents. Additionally he’s a member of the ITG committee Microwave Engineering (VDE) and the IEEE MTT-27 Technical Committee (wireless enabled automotive and vehicular applications). He is a reviewer for multiple IEEE transactions and letters. In 2015, he served as TPC chair for IEEE MTT-S International Conference on Microwaves for Intelligent Mobility.
The principle of enhancing the angular performance of imaging radars by exploiting the virtual aperture of MIMO systems is known and used since almost two decades. The presentation shows how the MIMO principle in radar is applied at millimeter-wave frequencies for automotive and UAV applications. Exemplarily, systems consisting of single and multichannel MMICs are shown up to 160 GHz. Furthermore, new approaches extending the classical view on MIMO systems are presented. First, a biologically inspired approach is shown, allowing realizing extremely small MIMO arrays on MMICs. Second, networks of many MIMO radars are discussed, resulting in huge coherent systems consisting of simple sensors.
