Dr.-Ing. Toralf Renkwitz studied Information Technology and Electrical Engineering at the University of Rostock, specializing in high-frequency engineering, measurement technology, and radar calibration. He currently serves as Deputy Head of the Radar Remote Sensing Department at the Leibniz Institute of Atmospheric Physics and was appointed Honorary Professor at Hochschule Wismar in 2024. 

He is Principal Investigator of the Partial Reflection Radars in Saura, Norway, and Juliusruh, Germany, as well as the MMARIA/SIMONe Germany radar network, and serves as Co-Principal Investigator of MAARSY (Norway). Dr. Renkwitz also contributed to the development of EISCAT 3D by designing the first antenna element prototype and performing substantial simulations of potential antenna arrays for the next-generation radar system.

His expertise spans radio science, radar calibration, signal processing, and atmospheric radar data analysis. His research addresses long-term changes in the middle atmosphere, mesospheric electron densities, particle precipitation processes and wind dynamics in the mesosphere and lower thermosphere, and atmospheric vertical coupling.
