Title
(DE) RÜCKSTRAHLER
(EN) RETROREFLECTORS
(FR) RÉTRORÉFLECTEURS
Abstract
(EN)
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.

(FR)
La présente invention concerne un système de rétroréflecteur comprenant un panneau de corps externe accouplé à un véhicule, le panneau de corps externe étant conçu pour permettre à un signal radar provenant d'un dispositif radar externe de passer à travers le panneau de corps externe. Le système de rétroréflecteur comprend également une pluralité de rétroréflecteurs intégrés dans le véhicule, la pluralité de rétroréflecteurs étant conçue pour réfléchir le signal vers la source de signal externe en tant que signal réfléchi, et la pluralité de rétroréflecteurs étant conçue pour présenter une réflectivité de crête pour une plage de longueurs d'onde radar ou une plage de longueurs d'onde lidar (détection et localisation par la lumière).
