摘　　要：主要研究了应用于24GHz车载雷达天线的匹配网络,根据工程中的实际需求介绍了阵列天线的馈电网络的分类及设计,通过比较得出了采用切比雪夫分布的不等分馈电网络比传统馈电网络拥有更低的副瓣电平和更高的主瓣宽度,最后通过契比雪夫综合法设计了一款馈电网络,经过仿真和测试满足24GHz车载雷达天线的需要。The paper mainly studies the design of matching network applied to 24Ghz vehicle radar antenna.According to the actual requirements in the project,the classification and design of the feeding network of array antenna are introduced.By comparison,the unequal distribution with Chebyshev distribution is obtained.The electrical network has lower sidelobe level and higher main lobe width than the traditional feeder network.Finally,a feeder network is designed by the Chebyshev synthesis method,which is simulated and tested to meet the needs of 24G vehicle radar antenna.
