The award of the Gisela und Erwin Sick Stiftung for the best masterthesis in 2021 at the Technical University Hamburg went to our Ph.D.-student Bartosz Tegowski fro his thesis „Measuring Principle for the Determination of the Antenna Phase Center“. His works shows a new theoretical approach for the characterisation of antennas for precise anglemeasurements with radar systems that was validated in measurements.
