本文介绍了首款用于汽车雷达的 16 元件 77-81 GHz 相控阵接收器。硅相控阵芯片采用非常低成本的技术封装，并连接到 16 元件线性微带天线阵列。包装的设计目的是<;即使使用焊线，通道之间的耦合也为 -28 dB。测量的图案显示扫描范围为 ±50o，并且与模拟结果非常吻合。 16 元件相控阵接收器与发射器一起实现，可显示户外驾驶场景中目标和场景的详细图像。
This paper presents the first 16-element 77-81 GHz phased array receiver for automotive radars. The silicon phased array chip is packaged using very low-cost techniques, and is attached to a 16-element linear microstrip antenna array. The packaging is designed to result in <; -28 dB coupling between the channels even with wirebonds. The measured patterns show scanning to ±50o and agree well with simulations. The 16-element phased array receiver has been implemented with a transmitter and shows detailed images of targets and scenes in outdoor driving scenarios.
