Autonomous and semi-autonomous vehicles rely on a complex hardware and software architecture to gather and exploit information from numerous radar sensors. To generate reliable data, the sensors require an unobstructed view of the surroundings. The bumpers or radomes mounted in front of the sensors must not impair radar functionality. This requires extensive testing of the deployed plastic parts and their underlying polymer structure. The R&S®QAR50 is the ideal tool to characterize the material properties of polymers and their influence on the quality of the radar signal at an early design stage and in quality control of material development.

Automotive radar sensors concealed in bumpers must transmit in the correct frequency domain. To hide the sensors, radar-transparent areas are usually painted the same as the rest of the vehicle. You need to know bumper material propertiers when selecting paint and coatings. In the past, quasi-optical or waveguide based setups with vector network analyzers (VNA) were used. This application card describes a simplified material characterization method in the automotive radar frequency domain (76 GHz to 81 GHz) using the R&S®QAR50 automotive radome tester.
