Abstract:
A method for a radar sensor, in particular a radar sensor for motor vehicles. The method includes the steps: determining, for particular evaluation channels that correspond to different central antenna positions of relevant transmitting antennas and receiving antennas in one direction, and for particular individual radar targets, a respective individual radial velocity of the particular radar target associated with the particular evaluation channel, based on signals obtained in respective evaluation channels; estimating a particular velocity of the particular radar target based on the determined individual radial velocities of the radar target, the velocity including information concerning a velocity in the forward direction in relation to the radar sensor, and a tangential velocity; and associating radar targets as belonging to an extended radar object as a function of the estimated velocities of the radar targets. A radar sensor is also described.
