研究并提出了两种用于汽车应用的具有多芯片组件的雷达前端配置。一种配置同时适用于 FMCW 雷达和扩频雷达，只需更换基带模块即可通过数字合成器实现； “软件定义雷达”的概念可以从这个角度来阐述。另一种配置是传统的 FMCW 雷达设置。雷达收发器模块采用了市售的 MMIC 和新型基板集成喇叭天线。前端的功能已通过一组实验室雷达测量得到验证。
Two configurations of radar front-end with a multi-chip assembly for automotive applications have been studied and presented. One configuration is suitable for both FMCW radar and spread spectrum radar with the replacement of a base-band module that could be realized by a digital synthesizer; the concept "software defined radar" could be addressed from this prospective. The other configuration is a conventional FMCW radar setup. Commercially available MMICs and a new substrate integrated horn antenna have been used for the radar transceiver module. The functionality of the front-end has been validated by a set of laboratory radar measurements.
