Radar for Automotive, UAV, and Industrial Applications

At the Institute of Microwave Engineering radar systems for novel applications in the automotive, industrial, and UAV branches are designed, and the corresponding signal processing is carried out.

The focus of the research activity is the development of the entire radar system and comprises both the front-end and back-end as well as the embedded radar signal processing. For this purpose, specific antennas are designed, passive RF-components are developed, and circuits for frequency synthesis, signal amplification, and filtering are conceived and manufactured.

The system design is done in different frequency ranges. For the buried landmine detection with drones in the project "Findmine" a UWB radar sensor with frequencies below 4 GHz is used. Research on a smartphone control using gesture recognition is done with a 77-GHz-MIMO radar. At these frequencies high resolution automotive radar sensors, new modulation schemes (CDM, OFDM), and interference topics are examined. The goal of another project is the 3-dimensional environment detection of UAVs with a 60/122-GHz radar. For industrial sensing a high resolution 160-GHz-FMCW-radar MMIC is developed. This radar chip is extended with a mechanical flexible antenna and used for novel radar applications in the project ZAFH MikroSens.
