Abstract
A method for determining a degree of blindness of a radar sensor in a motor vehicle on the basis of a measurement of the receive power level of a radar echo, including the following steps that are carried out when at least one object is located by the radar sensor: determining an expected value for the radar scatter cross-section of the object on the basis of known properties of objects to be located; estimating the radar scatter cross-section of the located object on the basis of the measured receive power level; and calculating an indicator for the degree of blindness of the radar sensor as a monotonically increasing function of the difference between the estimated radar scatter cross-section and the expected value.
