The interest in the deployment of imaging technologies at airports, check points or other security relevant areas lead to the development of different active and passive imaging systems in the millimeter-wave (mmW) range. This was also encouraged by the enormous advances made in semiconductor technology over the last few years, offering high integration densities with moderate costs.
This presentation deals with the design and technological aspects of a fully electronic multistatic imaging system (R&S QPS: Quick Personnel Security) developed for close range applications in the frequency range 70 GHz to 80 GHz. After reviewing the sparse array design, the resulting imaging properties and technological aspects advanced approaches like multipath imaging are presented. Finally the application of mmW imaging for nondestructive evaluation and quality assurance is discussed.
Frank Gumbmann received the diploma and the Ph.D. degree in electrical engineering from the University of Erlangen-Nuremberg, Erlangen, Germany, in 2005 and 2011, respectively. From 2005 to 2012 he was with the Chair for Microwave Engineering and High- Frequency Technology, University of Erlangen-Nuremberg, dealing with the design of sparse antenna arrays for short-range imaging and radar signal processing.
Since 2012 he has been working as an R&D Engineer in the Microwave Imaging Department, Rohde & Schwarz, Munich, Germany. His research interest is in the field of millimeter-wave measurement techniques, radar imaging systems and radar signal processing.
