Abstract: An FMCW radar device for determines the distance of an object from an element of the radar device. An FMCW radar device is disclosed having a predetermined time interval for the change in radar frequency of 100 ?s or less, a controllable oscillator configured such that while the radar device is operating the radar frequency can be tuned within the predetermined time interval via a tuning bandwidth of at least 4 GHz, and a phase comparator configured such that same provides a phase stabilisation of the generated radar signal for at least 900 frequencies of the radar signal within the tuning bandwidth of the controllable oscillator and within the predetermined time interval.
