Rabe rabe@hft.uni-hannover.de E. Denicke G. Armbrecht T. Musch I. Rolfes Leibniz Universität Hannover, Institut für Hochfrequenztechnik und Funksysteme, Appelstr. 9a, 30167 Hannover, Germany Ruhr-Universität Bochum, Lehrstuhl für Elektronische Mess- und Schaltungstechnik, Universitätsstr. 150, 44801 Bochum, Germany In a multitude of applications like e.g. in automotive radar systems a localization of multiple passive targets in the observed area is necessary. This contribution presents a robust approach based on trilateration to detect point scatterers in a two-dimensional plane using the reflection and transmission information of only two antennas. The proposed algorithm can identify and remove ambiguities in target detection which unavoidably occur in certain target constellations in such a two-antenna configuration.
