Claim One:
1. A method for determining the distance (R) and radial velocity (v) of an object in relation to a measurement location, with which radar signals are transmitted and following reflection at the object are received again at the measurement location, wherein the transmitted radar signals are subdivided within a measurement cycle into numerous segments, in which they are varied in their frequency from an initial value (f A , f B ) to a final value, and the received reflected signals are subjected over a segment in each case to a first evaluation for detecting frequency peaks and additionally a subsequent second evaluation of the signals is carried out for the frequency peaks of all segments of the measurement cycle to determine a Doppler frequency component as a measure of the radial velocity (v), wherein the segments are subdivided into at least two groups (A, B) whose initial value (f A , f B ) and/or final value of the varying frequency are different, where the segments of each group have the same form and the same initial values and final values, the segments of different groups are different with respect to initial values and final values, and the segments of each group (A, B) are separately subjected to the second evaluation and that elimination of ambiguities of the determined velocity is carried out by determining a phase difference of the mutually corresponding signals arising during the second evaluation of the segments of each group (A, B).
