Abstract: The invention relates to a method for determining the distance (R) and relative speed (v) of at least one object remote from an observation point, comprising the following method steps: continuous transmission of at least one first and one second electromagnetic signal in each case of a signal period (Tchirp) from the observation point; the signals consist of signal portions (bursts) having a constant frequency and a predetermined equal duration, wherein the signal portions of a signal cover a predetermined modulation range by means of frequency steps; the signals are transmitted interlaced in that signal portions of the different signals follow one another in time, wherein a frequency hop occurs between the successive signal portions of different signals, receiving the signals reflected by the object as an echo signal and carrying out a mixed operation with the transmission signal for transformation of the received signal into the baseband in a common analog channel; carrying out an analog-to-digital conversion and sampling the received signal portions of the echo signals and extraction of at least one sampling value for each signal portion; separately evaluating the sampling values for the different echo signals of the different emitted signals by means of a Fourier transformation stage and determining the frequency of the peaks corresponding to signal portions and determining a phase difference between the echo signals of the transmitted signals, characterised in that the signal portions of the second signal (B) are transmitted by means of the same frequencies as corresponding signal portions of the first signal (A).
