We present a fully polarimetric frequencymodulated
continuous-wave (FMCW) radar prototype and show its performance by polarimetric measurements of a dihedral corner reflector. The radar prototype operates at a frequency of 77 GHz and is built up by an FMCW frontend
(FE) and a multichannel baseband board. The FE consists of
horizontally and vertically polarized transceiver channels to conduct co-polarized and cross-polarized measurements. To
demonstrate the capability of the system, we placed a dihedral corner reflector on a turntable facing the radar system. Then measurements of the corner?s scattering parameter, depending on its rotation angle, were taken. To confirm the measurement results, we ran simulations using a self-developed numerical field simulation tool and compared the results to the measurements.
