Beschreibung
Zusammenfassung:	During operation, transmitters in the electronic device provide first and second FMCW radar signals, where carrier frequencies of the first and the second FMCW radar signals have a predefined variation as a function of time over a predefined frequency range, and the predefined variation as a function of time of a second carrier frequency of the second FMCW radar signal has a predefined delay relative to the predefined variation as a function of time of a first carrier frequency of the first FMCW radar signal. Furthermore, at least a receiver in the electronic device receives first and second reflected FMCW radar signals within a bandwidth of the receiver, where, at a given time, a frequency difference between carrier frequencies of the first and the second reflected FMCW radar signals, which corresponds to the predefined delay, is less than the bandwidth (and which may be less than a predefined value).
