Vehicle Integration
Since RADAR waves can penetrate plastics, the sensor integration is possible behind the bumper fascia
and thus invisible from the exterior. However, the plastic and other materials which surround the sensor
may cause bending, refraction and reflection of the RADAR waves. Distances, clearances, selected radii
and other constructive elements in their arrangement can lead to constructive or destructive interference
of the RADAR waves. That must be avoided by choosing a suitable integration position.
The sensors should be positioned in the vehicle at a height of 400 to 700 mm above the road surface. If
that cannot be fulfilled, then the deviating installation height must be agreed upon with Hella GmbH. &
Co. KGaA.
Warning:
The radar sensor should be installed and operated with minimum distance of 20 cm between
the radiator and the human body.
3.1 Spatial orientation of the sensors
The RS5.5 sensors can be mounted in the front and/or rear area of a vehicle under defined angles:
Rear side integration:
approx. 45 deg
Front side integration:
approx. 45 deg
