A method of measuring elevational misalignment of an automotive radar sensor in a factory or service setting utilizes two or more targets that can be discriminated by the radar system. The targets are positioned at different elevational angles with respect to the desired elevation axis, and the degree of elevational misalignment is determined according to the ratio or difference in return signal amplitude for the two targets. Discrimination of the targets may be ensured by differences in range, azimuth angle or Doppler. Since the amplitude difference is a measure of misalignment, the measurement may be used to verify proper alignment or to indicate the amount of adjustment required to achieve proper alignment.
