Vita

Christina Knill received the B.Sc and M.Sc. degrees in electrical engineering in 2013 and 2015, respectively, from Ulm University. 

In 2015, she joined the Insitute of Microwave Engineering as an research assistant with research focus on digital radar signal processing. 

Since 2022, she is a postdoctoral research fellow at the institute with research focus on radar signal processing and compressed sensing for UAV-based SAR.

Research

  • radar signal processing
  • novel modulation and multiplexing approaches for digital radars with focus on OFDM and code modulation
  • compressed sensing for radar
