White paper: Fundamentals of Radome and Bumper Measurements Using the R&S®QAR

Published by Rohde & Schwarz Inc.

New technologies in the automotive industry depend on how well the vehicle can interpret the surroundings. High-quality cameras are used to detect and keep lanes, assist with interpreting signs and parking, and ultrasonic sensors are used to detect objects in the near vicinity.

Another important set of sensors are automotive radars that are used in measuring the velocity and distance of other moving objects, making them a crucial tool for the future of autonomous driving.

Radar sensors are not obscured by fog or rain and because of the frequency they use they are not disturbed by either bright light or complete dark. Still, due to design challenges, radar sensors are usually hidden behind bumpers or emblems, which can influence how well the radar sensor can interpret the incoming data. Ideally, radomes are a structural enclosure for the radar that does not attenuate the electromagnetic signals transmitted or received, making them effectively transparent.

In real world, materials used and the design of radomes can interfere with the desired frequency band and cause angular errors, distortions and strong attenuation. The R&S®QAR automotive radome tester is an ideal solution during production to ensure proper functioning of the radar sensors.To find out more about the fundamentals of radome and bumper measurements by using the R&S®QAR quality automotive radome tester, download the white paper.

This white paper also deals with the measurement principle and highlights some important instrument features the operator needs to take into account when performing tests.
