Abstract
In a method of adjusting the axis of a car on-board radar, especially, a car on-board mono-pulse radar having the function of transmitting radio waves, light or ultrasonic waves, a car axis and an offset axis are set and the mount angle of an antenna offset-mounted on the offset axis can be adjusted with high precision and with ease through a reduced number of process steps. In the method, at least two points are set on the car, at least two isosceles triangles having a common base defined by a line connecting the setting points and sides of different lengths are drawn, a line connecting vertexes on the same plane of the obtained isosceles triangles and an extension of that line are determined as the car axis, the radar antenna is mounted on the car at an offset position which is apart from the car axis by a constant distance in the horizontal direction, a straight line parallel to the car axis and passing through the offset position is determined as the offset axis, a reflector is disposed in a direction at a constant azimuth angle as viewed from the offset position of the antenna, and the reflector is used as a detection target of the radar to adjust the mount angle of the radar …
