Abstract (en)
[origin: WO2019211010A1] The invention relates to a method for monitoring a FMCW radar sensor and to a FMCW radar sensor which has a plurality of local oscillators (32), in which method a first local oscillator signal of a first local oscillator (32) of the local oscillators is mixed with a second local oscillator signal of a second local oscillator (32) of the local oscillators in a mixer (38) to a baseband signal and the baseband signal is evaluated, a fault being detected by means of a result of the evaluation. In particular, it relates to a method for monitoring a FMCW radar sensor as well as a FMCW radar sensor, which has a plurality of high-frequency components (10, 12, 14, 16), which in each case have a transmitting and receiving part (20) for output of a transmission signal to at least one antenna (26) associated with the high-frequency component and for receiving a reception signal from at least one antenna (28) associated with the high-frequency component.
