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.
A method of detecting a horizontal error which is an error in a horizontal plane between a scanning center line of a scanning type radar device mounted on a vehicle and the vehicle's traveling direction during straight line driving where a steering angle of the vehicle is substantially zero, comprising:
A method of detecting a horizontal error which is a deviation in a horizontal plane of a scanning center line of a scanning type radar device mounted on a vehicle with respect to the vehicle's traveling direction dung straight line driving where a steering angle of the vehicle is substantially zero, comprising:
An apparatus for detecting a horizontal error which is an error in a horizontal plane between a scanning center line of a scanning type radar device mounted on a vehicle and the vehicle's traveling direction during straight line driving where a steering angle of the vehicle is substantially zero, comprising:
