Abstract
A method for ascertaining and compensating for a misalignment angle of a radar sensor of a vehicle, includes generating a first set of data which contains information about a measured alignment of the radar sensor with respect to an instantaneous movement of the vehicle; generating a second set of data which contains information about a measured alignment of the reference axes defined at the vehicle with respect to the instantaneous movement of the vehicle; ascertaining a misalignment angle by comparing the generated first set of data to the generated second set of data; compensating for the ascertained misalignment angle by changing an emission direction of the main lobe of the antenna characteristic as a function of the ascertained misalignment angle.
