该论文提出了一种工作于24-26GHz的4通道4波束时空RAKE雷达收发机，采用90nm CMOS工艺，用于车载雷达应用。通过多天线MIMO技术和时空RAKE处理，有效对抗多径反射干扰，提升雷达在复杂环境中的检测能力。
is a future environment that is adaptive and responsive to the objects and human beings that occupy it. Wideband RF and mm-Wave radar and imaging sensors will play a key role for indoor and outdoor surveillance, search and rescue, intelligent transportation and automotive activesafety systems, and wireless health monitoring [1]. Much like wireless-communication systems, radar and imaging sensors are adversely affected by multipath reflections caused by the presence of multiple targets. However, similar to wireless-communication systems, multi-antenna radar transceivers, or MIMO radars, may be envisioned that mitigate, and even harness, multipath for improved performance. For example, multipath reflections potentially enable a radar to probe an object from directions not visible
