Abstract
A marker used to detect an axial deviation of a radio wave axis Ar of a radar unit is provided in front of the radar unit and outside a radar field of view range set based on a field of view angle θ of the radar unit on a vehicle. A relative position between the radar unit and the marker is different between before and after an axial deviation of the radio wave axis Ar of the radar unit occurs. Thus, an axial deviation (an amount Δθ of axial deviation in an azimuth direction and an amount Δα of axial deviation in an elevation angle direction) of the radio wave axis Ar of the radar unit can be detected by obtaining a difference in marker detection position before and after the axial deviation by the radar unit.
