A method for producing a waveguide in a multilayer substrate involves producing at least one cutout corresponding to a lateral course of the waveguide in a surface of a first layer arrangement comprising one or a plurality of layers. A metallization is produced on surfaces of the cutout. A second layer arrangement comprising one or a plurality of layers is applied on the first layer arrangement. The second layer arrangement comprises, on a surface thereof, a metallization which, after the second layer arrangement has been applied on the first layer arrangement, is arranged above the cutout and together with the metallization on the surfaces of the cutout forms the waveguide.

A method is proposed for determining at least one calibration parameter for a radar system having a first radar transceiver and a second radar transceiver. The method includes performing a first calibration measurement and a second calibration measurement. The first calibration measurement and the second calibration measurement both include generating a first frequency-modulated oscillation signal and a second frequency-modulated oscillation signal, and combining the first oscillation signal received via the second terminal with the second oscillation signal, in order to generate a first difference signal for the first calibration measurement and a second difference signal for the second calibration measurement, both having a frequency difference between the first oscillation signal and the second oscillation signal. The method also includes determining the at least one calibration parameter based on the two difference signals generated for the first calibration measurement and for the second calibration measurement.
