Abstract
The invention relates to a radar detection system for a vehicle, with radar detection system including a radar sensor configured to emit/receive a plurality of radar waves, a lighting element arranged facing the radar sensor and including at least one light source configured to emit light rays, and a plurality of layers including a transparent layer configured to propagate the light rays, with the layers have substantially equal dielectric permittivities.
Claims4
A radar detection system for a vehicle, the radar detection system comprising:
- a radar sensor configured to transmit/receive a plurality of radar waves,
- a lighting element arranged facing the radar sensor and including at least one light source configured to emit light rays, and a plurality of layers including a transparent layer configured to propagate the light rays with total internal reflection,
- wherein the layers have substantially equal dielectric permittivities, with the transparent layer being a light guide and having the light guide being between a dark layer and a reflective layer, the reflective layer configured to produce a pattern and wherein the dark layer is between the radar sensor and the light guide.
