| 摘 要： | 针对现有镜面单锥TEM室用作脉冲电场传感器校准时存在测试尺寸空间较小、低频响应较差、内部与环境反射影响测量准确度等问题，采用超大型精密单锥结构、终端阻抗加载和低反射异形电波暗室等方法，在仿真优化分析基础上，设计研制了基于超大型低反射镜面单锥的脉冲电场标准装置。该镜面单锥母线长2 m,能够适应脉冲宽度大于5 ns的脉冲信号，整体装置所产生的标准脉冲电场幅值50～150 V/m可调、脉冲前沿小于100 ps、脉冲宽度大于5 ns,满足装备测试脉冲电场传感器的大空间、宽频带、高准确度校准需求。

| Abstract: | In view of the problems of small test size space, poor low-frequency response, and internal and environmental reflection
affecting measurement accuracy when the existing specular monocone TEM cell is used as the calibration of pulsed electric field sensors,
the standard device of pulsed electric field based on ultra-large low-reflection specular monocone is designed and developed on the basis
of simulation optimization analysis by using ultra-large precision single-cone structure, terminal impedance loading and low-reflection
special-shaped anechoic chamber. The generatrix of the monocone is 2 m long and can adapt to pulse signals with a pulse width greater
than 5 ns, and the amplitude of the standard pulse electric field generated by the device is 50~ 150 V/ m, the rise time of the pulse is
less than 100 ps, the pulse width is greater than 5 ns. This standard device meets the needs of large space, wide frequency band and
high accuracy calibration equipped with test pulse electric field sensors. |
