摘　　要：以闪电定位仪系统为应用背景,着重研究了雷电低频有源天线的设计,用30 cm的圆盘作为接收设备,其性能优劣直接影响探测目标的准确性。本文主要设计任务是由圆盘天线接收闪电信号,将接收到的雷电低频信号经过VCA810集成运放电路放大,能够正确地显示出相应发射频率的波形,接收效果较好,同时软件仿真结果和硬件试验结果对比验证了本文设计的可靠性。Based on lightning location system as the application background, the design focuses on the lightning low frequency active antenna, using 30 cm disk as a receiving device, its performance directly affects the accuracy of target detection. The main design task of this paper is to receive lightning signal by the disk antenna, and then the lightning low frequency signal is amplified by VCA810 integrated operational amplifier circuit amplifier, to correctly display the corresponding emission frequency waveform, and the receiving effect is good. The comparison between the software simulation and hardware test results verifies the reliability of the design in this paper.
