Abstract :

RF-sensors and Radar systems found their way into civil and industrial applications decades ago. Since then, they reliably measure distances, velocities, and filling levels etc. contact free and with great accuracy. Lately, current trends and technological achievements pushed operating frequencies up to the millimeter wave range, which allows for the determination of various additional physical quantities. Consequently, these novel sensors can be utilized in numerous areas of process industry, civil protection, and daily life. Therefore, their main purpose will be the determination and investigation of environmental parameters that allow for the supervision of crucial system parameters and the interpretation of complex processes. The talk will give an overview on diverse RF‐sensors for different applications, which were explored at the Ruhr‐University Bochum within recent years. The presented sensor applications include: humanitarian demining, mmWave imaging, contact‐free gas sensing, as well as dust and particle determination for process industry and natural hazard protection. Next to the introduction of the numerous areas of application, the different sensor designs will be explained and their field applicability verified. Moreover, opportunities regarding student exchanges between Ruhr-University and Lille University will be introduced and discussed.

About the lecturers:
Christoph Baer received his diploma and doctor degree in electrical engineering at Ruhr-University Bochum in 2009 and 2015, respectively.
