Abstract: A motor vehicle having at least one radar sensor, which is mounted behind a radome, formed by a component of the motor vehicle to be radiated through, and/or having a radome, wherein the motor vehicle further includes a reference structure having at least one radar-detectable marker, which can be controlled by an adjusting apparatus and moved into a measuring position in the detection area of a radar sensor outside the radome, and a control apparatus configured to control the adjusting apparatus, based on a trigger signal, for moving the reference structure into the measuring position and to evaluate radar data recorded by the radar sensor describing the reference structure in the measuring setting through a comparison with a comparison data set stored in the control apparatus and recorded without deposition on the radome for detection of the potential deposition. The trigger signal indicates a potential deposition, which restricts the performance of the radar sensor, on the radome.
