【摘要】 空中电场是以三维矢量形式存在的,以往用于空中电场探测的电场传感器主要实现矢量电场的一个或两个分量的探测。介绍了一种新型的空中三维电场传感器,可实现空中矢量电场的三维检测,并对该三维电场传感器的标定方法进行了仿真分析,设计出该传感器的专用标定装置。测试数据表明该传感器的输出与外部电场呈良好的线性关系,与理论分析一致,证明了该电场传感器结构设计和标定方法的合理性。更多还原

【Abstract】 The spatial electric field is a threedimensional(3D) vector.Previous electric field sensors only measure one or two dimensions of the spatial electric field.A novel 3D spatial electric field sensor for measuring 3D electric field was presented.The method for calibrating the sensor was simulated and analyzed.The dedicated calibration instrument was designed.Measurement results show that the output of the sensor varies linearly with the electric field,which is in accord with the theoretical analysis.The rationality of the design of the sensor and the calibration method is proved.更多还原
