5.3.3 Effect of Type- and Thickness of Fascia Material
Autoliv has examined various fascia material samples with a thickness
of 2.5 – 4 mm. Fascia loss effects can be optimized by proper control
of the material thickness and dielectric constant. Thickness should be
uniform in front of the radar sensor.
Thickness and dielectric constant must be controlled to a tolerance of
±10% max to ensure optimal performance.
New fascia material shall be evaluated by Autoliv for its characteristics
at RF antenna frequency.
5.3.4 Effect of the Paint
Effect of paint is detailed in Appendix A. New paint material shall be
evaluated by Autoliv.
5.3.5 Smoothness of Fascia in Front of Antenna
Avoid sharp vertical or near vertical character lines in front of sensor
antenna. Horizontal character lines seem to have little effect on sensor
performance.
