Abstract
A method to determine a horizontal error of a radar device mounted on a vehicle along with the mounting error or imbalance in the diameters of wheels based on an echo signal from a reflector provided on a road. A vehicle's traveling locus is stored in advance as a reference locus obtained from the distance L between the vehicle and reflector and the direction .theta..sub.R. A traveling locus when the vehicle is actually traveling in a straight line where the steering handle is kept in a neutral position is compared with the previously stored reference locus. A horizontal error is obtained from the traveling locus on the coordinate axis .theta..sub.R and the shift from the reference locus.
