Brief description

Quick and intuitive evaluation of 76 to 81 GHz automotive radomes and bumpers

The R&S®QAR is the ideal tool for characterizing automotive radomes and bumpers in R&D and production. Unlike current production measurement methods, the measurement is independent of a golden device radar and requires far less floor space than a setup using several corner reflectors. Since the R&S®QAR is very simply to operate and delivers easy-to-interpret results, its many capabilities can significantly speed up development processes.

Features & benefits

Reflectvity and homogeneity

Detailed analysis of the homogeneity of automotive radomes in the mmWave domain

Thanks to its hundreds of antennas, the R&S®QAR provides a high-resolution, spatially resolved image of the reflectivity of automotive radomes and bumpers in the mmW domain. Parts with high variation, anomalies, or large gradients in terms of reflectivity in the material can be clearly identified. A threshold for the mean reflectivity and its standard deviation support simple pass/fail tests in a production environment.

One-way transmission loss

Frequency-selective analysis of the transmission loss of automotive radomes

An optional, external transmit antenna is available for the R&S®QAR to perform transmission loss measurements. The measurement is frequency-selective and therefore clearly highlights any mismatches within the radar transmitter’s field of view.

Mounting position measurement

Determining the mounting position of automotive radar sensors

Automotive radar sensors are usually integrated invisibly behind vehicle bumpers or brand emblems (radomes). For the sensors to operate as expected, they must be installed in the intended location precisely behind the area of the bumper or radome that is transparent to radar signals. The R&S®QAR equipped with the R&S-K100 Software allows pushbutton checking of sensors behind already installed bumpers or radomes for radiation in the right direction and a free view of the surrounding area.
