One embodiment includes a radar system for range measurement having a first operating mode for measurement in a first range zone and having a second operating mode for measurement in a second range zone. The radar system includes a radio-frequency transmission module, at least one antenna, and a control and processing unit. The radio-frequency transmission module has an oscillator for providing a transmission signal with a first frequency spectrum in the first operating mode, and with a second frequency spectrum in the second operating mode. The at least one antenna is connected to the radio-frequency module. The control and processing unit provides control signals which are supplied to the radio-frequency transmission module for selecting the operating modes.
