Automotive radar sensors can be well hidden behind bumpers, but require to be transmissible in the respective frequency domain. To effectively hide the sensors, the radar-transparent areas are usually required to have the exact same shade of color as the rest of the vehicle. To select proper colors and coatings for such bumpers, the respective material properties must be known. In the past, either quasioptical or waveguide based setups, both using vector network analyzers (VNA), have been used. This application card demonstrates a simplified method for material characterization in the automotive radar frequency domain (76 GHz to 81 GHz) based on the R&S®QAR50 automotive radome tester.

自主和半自主车辆通过复杂的硬件和软件架构收集和利用多个雷达传感器传输的信息。为了生成可靠的数据,传感器需清楚探测周围环境。传感器前方安装的保险杠或天线罩不可影响雷达功能。这需要对所用塑料零件及其底层聚合物结构进行各种测试。R&S®QAR50 非常适合在早期设计阶段和材料开发的质量控制阶段表征聚合物的材料特性及其对雷达信号质量的影响。
