Abstract

A pathway article that includes a radar reflective structure with a large radar cross section (RCS) in a compact planar structure. The radar reflective structure may include a plurality of elements that act as antennae and may be spaced appropriately on a planar surface creating a radar reflecting surface. The antennae may be slots in a conductive sheet, or conductive strips. Selecting the spacing between the antennae may cause constructive interference and reflection substantially opposite the direction of the incident radar radiation. Pathway articles may also include at least one additional feature that may be detected by other sensors. Examples of other features include retroreflective features detectable by the human eye, visible camera and similar sensors. This redundancy in the detectable features of the pathway article may enable use of sensor fusion to provide greater confidence of detection of the pathway article under a wide range of conditions.
