| 摘 要： | 介绍了脉冲电场微分测量和原始波形测量的基本原理,设计研制了一系列不同灵敏度的脉冲电场原始波形测量系统,分析了脉冲电场探测器的理论修正模型。该测量系统主要包括天线模块、积分器模块、放大和驱动模块以及光电传输模块,利用同轴型TEM小室对测量系统进行了时域标定。结果表明:测量系统的前沿响应时间小于1.0 ns,系统输出脉冲平顶在10.0μs内下降不超过5%,测量系统输出幅度与电场强度在20 dB的动态范围内呈线性关系,该系列探测器可以用来测量最小10 V/m、最大100 kV/m的电场强度,满足高空电磁脉冲标准环境的测量要求。 |

| Abstract: | The paper introduces the differential and original waveform measurement principles for pulsed E-field, and develops an pulsed E-field sensor based on original waveform measurement along with its theoretical correction model. The sensor consists of antenna, integrator, amplifier and driver, optic-electric/electric-iptic conversion module and transmission module. The time-domain calibration in TEM cell indicates that, its risetime response is shorter than 1.0 ns, and the output pulse width at 90% of the maximum amplitude is wider than 10.0 μs. The output amplitude of the sensor is linear to the electric field intensity in a dynamic range of 20 dB. The measurement capability can be extended to 10 V/m or 50 kV/m by changing the system’s antenna and other relative modules． |
