摘要
为了节省研发成本,缩短研发周期,方便电离层流动观测,设计了可用于1MHz^30MHz电离层回波探测的环天线,对该天线进行了辐射性能的仿真和天线阻抗的测量,设计了有源天线的前端信号放大电路。配合通用软件无线电平台USRP,组成了电离层高频回波探测系统,电离层扫频回波探测实验结果显示该天线能够宽频率范围工作,具有应用价值。
In order to save development costs, to accelerate the development life-cycle, A loop antenna for 1MHz^30MHz ionospheric echo detection is designed, Radiation performance simulation and antenna impedance measurement is investigated, The front end signal amplifier circuit of active antenna is designed.With USRP, a high frequency echo sounding system is for-med.This method can be used for broadband Ionosphere exploration.
