The radar sensor performance should be influenced as low as possible by the installation
behind a fascia. Therefore the two-way radar loss by the fascia should be as low as possible
and the reflection attenuation must fulfill the requirements listed below.
Vertical misalignment will cause additional attenuation reducing the maximum range.
Horizontal misalignment will cause reduced detection at higher azimuth angles.
Ghost target detection caused by interference signals of multiple reflection at fascia and metallic
parts of the vehicle must be avoided. A simulation can be offered to evaluate the risk and the
need of using absorber material to suppress this unwanted signal. Because the threshold of
detection is very low, a high attenuation is required. Plastic material can only achieve high
enough attenuation, if carbon black is added.

Radar cone

The radar cone describes the zone where the fascia has to be optimized. Any parts of the
vehicle inside the radar cone may influence the radar performance. Cables, brackets, bars etc.
should not touch the radar cone. The fascia in this zone may not have bends and edges as well
as changes in thickness or material or painting.
Based on the footprint on the top side of the radar PCB the cone is characterized by a vertical
and a horizontal opening angle. The footprint is centered regarding to the sensor housing. A
CAD model of the radar cone is available.
The footprint for radar cone has the following dimensions: (W x H) 55 mm x 55 mm
