摘要
设计制作了一种用于雷电磁场探测的磁场测量天线系统。该测量系统分为天线部分、数据处理部分和数据采集部分。利用函数发生器以及示波器对设计的数据处理电路进行标定后发现,电路能够不失真地放大天线部分感应的微弱信号,利用ICGS实验冲击平台并配合Tektronix TDS 2022对整个测量系统进行模拟雷电采集实验后发现,该测量系统能够很好地反应雷电的磁场变化。
An antenna system for lightning magnetic field detection is designed in this paper, which consists of antenna, data processing and data acquisition. The function generator and the oscilloscope are used to calibrate data processing circuit, and the results indicate that the proposed data processing circuit amplify weak signals induced by the antenna without distor- tion. A test of lightning simulation is carried out on ICGS and Tektronix TDS 2022, and the results indicate that the measure- ment system is able to accurately refect the variation of the magnetic field produced by the lightning.
