Abstract
A transponder (200) is attached to a laser alignment fixture (210) and used to align an automobile collision avoidance radar antenna boresite with the thrust vector of the vehicle. The alignment fixture (210) has attached reflectors for alignment with two laser beams. To align the collision avoidance radar, the transponder (200) is positioned along the thrust vector of the automobile using a first laser beam (203) aligned perpendicular to a wheel axle. The first laser beam (203) is aligned when transmitted from the wheel axle onto a first piece of reflective material attached to the alignment fixture (210). A second laser (216) is provided parallel to the centerline of the collision avoidance radar antenna to remove azimuth and elevation translation errors between the transponder antenna centerline and the collision avoidance radar antenna centerline. The second laser beam (216) is aligned when transmitted from the automobile onto a second piece of reflective material attached to the alignment fixture (210). The transponder (200) is then used to zero an angle (.alpha.) between the electrical boresite of the collision avoidance radar antenna and the boresite of the transponder anten…
