Abstract
An apparatus determines a lateral position of a land vehicle on a pathway, on a surface of which one or more microwave reflectors are distributed in a direction of travel of the vehicle. The microwave reflectors have reflectivity different from the surface of the pathway where no microwave reflectors are present. The apparatus comprises a radar sensor and a processor. The radar sensor is 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. The radar sensor is also configured to detect one or more reflections of the radar signal from the pathway. The processor is operatively connected to the radar sensor and configured to determine a lateral distance of the vehicle from at least one of the microwave reflectors.
