Method of setting the axis of a radar inside a vehicle which can detect at least one azimuth angle between the vehicle and a preceding vehicle

摘要

The method involves determining at least two points on the vehicle, forming at least two isosceles triangles with a common base defined by a line through the two points and with sides of different lengths, and defining a line connecting the apices (22,23) and its extension as the vehicle axis (5). A radar antenna is mounted on the vehicle at a point separate from the vehicle axis and a parallel line through this point defined as the offset axis. A reflector is placed at a point at an azimuth angle to the antenna position and used as the radar detection target to set the radar antenna angle so that the detected azimuth angle equals a desired value.
