An onboard millimeter wave system able to provide the real-time lateral position of the vehicle with respect to the guard rail is presented. The distance is measured from a reference line obtained by a 90/spl deg/ corner reflector embedded in the metallic guard rail. A modulation of the back scattering signal, obtained by interleaving corners with different size, allows the recognition of the reference line in unfavorable situations.
