3.2 Bumper or Obstruction Restrictions
3.2.1 Basic requirements
Ideal situation: The radar beam covers the direction without any metal parts or painted bumpers.
General situation: The corner radar is usually installed in the bumper at the rear of the vehicle, so
special attention should be paid to the material selection, shape design, paint and relative position
of the bumper or cover. At the same time, water droplets, water film and snow accumulation on the
surface of the occluder may cause additional signal attenuation and further lead to limited
performance and functionality.
3.2.2 Bumper Material Requirements
There should be no obstructions (including bumpers) in front of the radar. If the obstructions or
bumpers are unavoidable, the materials of the obstructions must have a small dielectric constant and
dielectric loss. These materials include Polypropylene, Polyamide, Polycarbonate, ABS (Acrylnitril-
Butadien-Styrol), PC-PBT (Polycarbonate Type), etc. These materials should reduce the use of metal
and carbon fiber, and the surface of the material should not contain metal or metal material coatings.
The following table shows the material parameters of commonly used bumpers or coverings.
