Abstract

A retroreflector system including an outer body panel coupled to a vehicle, wherein the outer body panel is configured to allow a radar signal originating from an external radar device to pass through the outer body panel. The retroreflector system also includes a plurality of retroreflectors embedded in the vehicle, where the plurality of retroreflectors is configured to reflect the signal to the external signal source as a reflected signal, and where the plurality of retroreflectors is configured to have a peak reflectivity for a radar wavelength range or a light detection and ranging (lidar) wavelength range.
