基于多普勒雷达射频技术的车辆探测前端电路设计
资料介绍
文中提出了一种基于多普勒雷达射频技术的探测电路, 与视频车辆检测和无线地磁车辆检测方法相比, 该设计不受天气或光线的影响, 提高了准确性, 整个电路由锁相环、 功分器、混频器和收发天线组成, 在测试各独立模块性能的基础上, 对整个电路进行了集成设计和实验测试, 实验结果表明, 输出信号的波动可以表明车辆的存在.
This paper proposes a detection circuit based on the technology of doppler radar rf, andcompared with video vehicle detection and wireless geomagnetic vehicle detection, the design is notaffected by the weather or light, improves the accuracy. The whole circuit consists of a phase-lockedloop, a power divider, a mixer and a transceiver antenna. On the basis of testing the performance of eachindependent module, the integrated design and test of the whole circuit are carried out. The experimentalresults show that the fluctuation of the output signal can indicate the existence of the vehicle.
