    摘要: In a method for checking the functionality of a mixer, the mixer is supplied with a high-frequency signal and a high-frequency comparison signal in order to generate a baseband signal. The amplitude of the high-frequency signal is modified as a function of time. A direct-current voltage component of the baseband signal which is output by the mixer is analyzed to determine the functionality of the mixer.

    摘要: A radar system includes at least two modules, each having a phase detector and a first high-frequency source and each having an antenna output and/or each having one or more antennas. At least two modules include a device for synchronization between the first high-frequency source of a first module of the at least two modules and the first high-frequency source of a second module of the at least two modules of the radar system. The phase detector has a first input for a first reference signal. The phase detector also has a second input for a first loop signal. A module for a radar system has the design of one of the modules of the radar system described above.

    摘要: The radar sensor has a transceiver device for generating a radar signal having a settable output power, a control unit and an interface unit. The transceiver device may be controlled via a digital interface via the interface unit and the control unit. One of the lines of the interface is connected to the control unit, the control unit being designed in such a way that when a predetermined level is present on this line, the output power of the transceiver device is lowered.
