Radar and light emitting arrangement for vehicles for emitting light and radar radiation, as well as method and use

In many cases, separate components were hitherto used in emitting light and radar radiation. Demand exists for a combined device, which can unify within itself the advantages of light and radar emission in device-technical synergies as well. A radar and light emitting arrangement (10) is provided for emitting light and radar radiation and for detecting at least reflected radar radiation, with: a headlight (1) with a light- transparent headlight covering (4) and a light source (2) and a light reflector (3); a radar module (11), with a radar antenna unit (12), arranged behind the headlight covering, integrated into the headlight; wherein the radar and light emitting arrangement (10) comprises at least one radar radiation shaping means (13, 14), in particular a frequency-selective radar radiation shaping means, including a radar radiation shaping means integrated in the headlight covering. The application of the radar technology arranged integrated into the headlight can hereby be further optimized. The inventio
