Research Group High Frequency Sensors and Radar Techniques

In three core areas, namely Sensor Principles & Development, Sensor Information Processing and High Level Information Extraction, the Center for Sensor Systems (ZESS) at the University of Siegen works on basic system developments with application areas in science and industry. The team is interdisciplinary with scientists from the areas of industrial and natural science. Fraunhofer FHR has engaged in a close cooperation with the working group for more than ten years, for example, within the framework of ambitious projects relating to bistatic SAR imaging.

The research group »High Frequency Sensors and Radar Techniques« works on innovative techniques for imaging radar under the leadership of Professor Joachim Ender (Director of Fraunhofer FHR up to 2016). The application of the compressive sensing theory, which, in the presence of a structured scene, can not only achieve equivalent results with just a few measurements but can also increase the quality of the image with additional capabilities, is of special significance.

Serving as a project partner of Fraunhofer FHR in the BMBF (Federal Ministry of Education and Research) project RAWIS (Radar Warning and Information System), new results for the MIMO imaging radar relating to the monitoring of buildings in danger of collapsing were obtained. Other themes of the working group within the framework of the DFG-funded project ComSAR include the extraction of more information from ISAR images through the utilization of physically motivated representation bases, 3D imaging with an ultra-broadband sensor, also for sub-surface imaging, and innovative terahertz techniques with hybrid pseudo-random aperture modulation.

Numerous promotions are supervised and implemented by the working group within the framework of the close interaction with Fraunhofer FHR.
