Fascia Classification (FR5CUEC)
The two-way radar loss caused by fascia should be as low as possible. High losses decrease
the sensor performance regarding range and angle estimation. Therefore it is recommended
to achieve a two-way radar loss below 3 dB.
Surface Properties of the fascia
The surfaces of the fascia shall not exceed an average roughness height of 20 µm
(corresponding to ISO 1302 class N10; VDI 3400 class 45).

6.3 Installation hints

To enable the full performance of the radar sensor, it is recommended to use the following
installation hints and guidelines for the RF integration of the sensor.
Maximum angle between radar cone and fascia
The angle α between the radar beam inside the radar cone and the fascia may not be larger
than 70° anywhere inside the radar cone.
