1. An apparatus for determining a lateral position of a land vehicle on a pathway on which one or more microwave reflectors are distributed on a surface of the pathway in a direction of travel of the vehicle, the one or more microwave reflectors having reflectivity different from the surface of the pathway where no microwave reflectors are present, the apparatus comprising:
a radar sensor mounted to the vehicle and configured to transmit a radar signal having a beam pattern center aimed downward from the vehicle toward the surface of the pathway and sideways from the vehicle generally perpendicular to the direction of travel of the vehicle, the radar sensor being further configured to detect one or more reflections of the radar signal from the pathway; and
a processor operatively connected to the radar sensor and configured to determine a lateral distance of the vehicle from at least one of the microwave reflectors on the surface of the pathway.
