Thesis

  • Currently my focus is radar localization. Therefore, I am always looking for students who want to develop hardware. You will learn to design your own circuit, which you will first simulate, realize on a printed circuit board and then characterize.
  • Furthermore, I am looking for students who are interested in radar signal processing in hardware. Here the full signal processing chain from signal synthesis to the receive path should be implemented in an FPGA. Since this is a very broad field, previous knowledge in FPGA programming (VHDL, Verilog) would be helpful.
  • Finally, I offer software related topics in Python. Here the focus is on the design of radar simulations and the development of localization algorithms based on radar data (often based on Kalman filters).

If you are interested in one of the topics in the course of a Hiwi activity/bachelor thesis/research internship/master thesis, then feel free to contact me via mail.
