A method for detecting an object in a surrounding region of a motor vehicle by means of a radar sensor with determination of dimensions of the object, a radar sensor, as well as motor vehicle driver assistance system

摘要

The invention relates to a method for detecting an object (4) in a surrounding region (5) of a motor vehicle (1), with which, by means of a radar sensor (3) radar signals are emitted and the of the object (4) reflected radar signals are received, on the basis of the radar signals, a received signal is determined from the received signal, a power spectrum (7) is determined, and which an intensity (i) of the received signal in a function of a distance (r) to the object (4) and a radial velocity (v_R) of the object (4) describes and, on the basis of the power spectrum (7) the object (4) is detected, whereby from the power spectrum (7) a profile (9) of the intensity (i) as a function of the distance (r) is determined, with the aid of the profile (9) a minimal distance value (r_min.) and a maximum distance value (r_{a maximum}) be determined and, on the basis of the minimum distance value (r_min.) and of the maximum distance value (r_{a maximum}) Dimensions of the object (4) are determined.n="22"
