简介

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

The R&S®QAR is the ideal tool for characterising automotive radomes and bumpers during R&D and production. Due to its comparability with vector network analyzer (VNA) based measurement setups, the R&S®QAR measurement results are compatible with existing setups for material characterization. The R&S®QAR is simple to operate with measurement results easy to interpret. Its unique features help to significantly speed up the development process of new radomes.

特性和优点

Measurement of design emblems

Detailed analysis of the homogeneity of automotive radomes in the radar frequency domain.

Using hundreds of antennas, the R&S®QAR creates a spatially resolved image of the reflectivity of automotive radomes in the mmW frequency domain. Parts of the radome with deviation reflection due to e.g. thickness or permittivity differences can be easily identified. Based on a threshold for mean reflectivity and standard deviation, automation software in production can make decisions on well defined pass / fail criteria. Optionally, the 1-way attenuation of the radome is measured.

Comparability of measurements

Comparability of transmission loss and reflection measurements with results using vector network analyzers (VNA).

The recorded results are comparable to reflection and transmission loss measurements using a vector network analyzer (VNA). The transmission and reflection parameters of the DUT are captured with software options R&S®QAR-K10 and R&S®QAR-K50. The measurements are non-destructive and therefore suitable for production and quality assurance tests. Thanks to its imaging capabilities, the measurement contains information regarding the correct positioning of the sample.

Extended homogeneity analysis

Localization of reflectivity variations.

Using the R&S®QAR-K20 software, it is possible to perform an even more detailed analysis of the reflection of design emblems. The upgrade enables the user to freely define an evaluation grid on the measurement results. The mean reflection and its standard deviation can be evaluated in each cell independently.

测量安装位置

测定汽车电子雷达传感器的安装位置

汽车电子雷达传感器通常隐蔽地安装在车辆保险杠或车标(天线罩)后面。要确保传感器按预期工作,必须将传感器精确安装在雷达信号可穿过的保险杠或天线罩后面的目标位置。R&S®QAR 可配备 R&S-K100 软件,能够一键检查已装保险杠或天线罩后面安装的传感器,以确保辐射方向正确且无障碍探测周围区域。
