An alignment rig (4) and a method for establishing the direction of emission D of a radar antenna (16) relative to a frame (2) of a vehicle (14) are disclosed. The rig comprises a display screen (20) arranged perpendicular to the longitudinal direction of the frame and fixed to the frame and arranged in such a way that the direction of emission (D) of the antenna falls on the screen. By sending a signal (26,27) towards the screen, which is directed in substantially the same direction as the direction of the antenna emission, makes it possible for the direction of antenna emission relative to the direction of movement (B) of the vehicle to be established on the basis of the position of the vehicle driving shaft (8) relative to the position of the frame and on the basis of the impact point (30) of the signal on the screen. |
