简介

快速直观地评估频段范围介于 76 GHz 至 81 GHz 的汽车电子天线罩和保险杠

R&S®QAR 非常适用于在研发和生产中进行汽车电子天线罩和保险杠特征校准。该仪器的测量与当前生产测量方法不同,无需使用标准设备雷达,且所需空间远小于使用多个角反射器的装置。R&S®QAR 功能丰富、操作简单并且能提供清晰易懂的测量结果,可以显著加快开发过程。

特性和优点

反射率和均匀性

详细分析毫米波范围中汽车电子天线罩的均匀性

R&S®QAR 采用数百个天线,可以生成关于汽车电子天线罩和保险杠的反射率的高分辨率空间分辨毫米波图像。因此,可以清楚确定反射率变化较大、异常或梯度较大的材料部分。利用平均反射率阈值以及标准差,可以在生产环境中进行简单的合格/不合格测试。

单向传输损耗

针对汽车电子天线罩的传输损耗执行选频分析

R&S®QAR 可采用外部发射天线选件,以便执行传输损耗测量。此测量属于选频测量,因此可以清楚显示雷达发射机视野内的任何失配情况。

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。
