摘要
目前电场传感器只能探测大气电场强度矢量一维或者二维方向分量,尚无法精确地反映空中电场强度大小。该文介绍一种结构新颖的小型三维空中电场传感器,由轴向(Z)和径向(X,Y)三路电场测量单元和驱动单元以及电路单元组成,用于探测电场强度的三维方向矢量。在地面实际测试中,传感器输出信号与电场强度的理论关系得到了验证,证明了三维电场传感器结构设计和检测方法的合理性。
Electric field sensors used at present are only capable of measuring one or two dimensional values of electric field intensity. A miniaturized electric field sensor used for measuring three dimensional electric field is introduced, which is composed of axial(Z) and radial(X, Y) electric field measuring units, driving unit and circuit unit. The practicability of the three dimensional electric field sensor is demonstrated, and it is shown that the theoretical prediction and experimental result are in good agreement.
