Abstract

An FMCW radar sensor having a plurality of antenna elements and a supply circuit for supplying transmission signals having ramp-shaped modulated frequencies to the antenna elements, including a switchover device for switching over the supply circuit between a near-field mode, in which the transmission signals supplied to the individual antenna elements have a certain frequency offset, and a far-field mode, in which the frequencies of the transmission signals are identical.
