To exceed the ambiguity limit of such an interferometric system a dual tone approach is used, extending the unambiguity range to several wavelengths. The system will be presented with measurement results at 24 GHz within a WR42 waveguide to prove the feasibility of the proposed concept.enDistance measurementInterferometryPhase measurementRadarSix-PortWaveguideConference Paper10.1109/EuRAD.2014.6991206Other
