摘要: 为了在雷达中实现对中距和长距的探测，首先研究并实现了针对中长距雷达探测需求的天线及其组阵形式，然后通过雷达方程得出天线阵列所需的增益与组阵方式，设计了高增益窄波束和低增益宽波束形式的毫米波雷达天线阵列，最后的仿真和测试结果表明，该中长距雷达天线阵列能够满足77 GHz车载毫米波雷达对中距大角度和长距小角度的视野范围探测需求。Abstract: In order to realize the medium-range and long-distance detection in one radar, we studied and realized a kind of antenna array meeting the long- and medium-range radar demand. The simulation and measurement results show that the radar antenna array can meet the detection needs of 77 GHz vehicle millimeter-wave radar of large angle with medium distance and narrow angle with long distance.
