Radar sensors integrated in vehicle headlamps
Autonomous vehicles require a large number of sensors - so many that vehicle developers are faced with the question of where these sensors can best be placed. A joint research project between various institutes provides an interesting answer: it is possible to integrate the radar sensors into the headlamps. Using a thin-film technology, these sensors can be installed almost invisibly in the headlamps.

In the RadarGlass joint project, the Fraunhofer Institute for Laser Technology ILT from Aachen, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP from Dresden and the Institute for High Frequency Technology IHF of RWTH Aachen University are working together. The researchers have developed a layer system that enables the integration of radar sensors into car headlights. "It's the perfect position because they cover the near and far range completely and also allow a view to the side," explains Patrick Gretzki, scientist in the Micro- and Nanostructuring Group at Fraunhofer ILT. Another advantage is the heat generated by the headlights, which ensures that the sensors are always free of ice and snow in adverse weather conditions and thus have an undisturbed view of the surroundings.
