Mechanical enclosure

It is possible to hide the sensor behind a so called ra-

dome (short for radar dome) to protect it from environ-

mental inﬂuences or to simply integrate it in the case of

the end product. A radar sensor can see trough diffe-

rent types of plastic and glass of any colour as long as

it is not metallized. This allows for a very ﬂexible design

of the housing as long as the rules below are observed.

– Cover must not be metallic.

– No plastic coating with colors containing metallic or

carbon particles.

– Distance between cover and front of Radar sensor

≤ 6.2 mm

– Best cover material is Polycarbonat or ABS

– Best cover thickness is 3 – 4 mm

– Vibrations of the Radar antenna relatively to the

cover should be avoided, because this generates

signals that can trigger the output

– The cover material can act as a lens and focus or

disperse the transmitted waves. Use a constant

material thickness within the area used for trans-

mission to minimize the effect of the radome to the

radiated antenna pattern.

Detailed information about the calculati-

on and thickness for different cover mate-

rials can be found in the application note

“AN-03-Radome”.
