Preliminary experimental investigation of field distribution characteristics in horizontally polarized bounded-wave EMP simulator with 9.5 m in height

  • 摘要: 测量了9.5 m高的水平极化有界波电磁脉冲模拟器的内部场,并根据实验测量结果分析了该模拟器内场分布特性,包括一定区域内场均匀性的定量分析及模拟器内部有效测试空间的确定方法,进而对最低位置为距离地面2 m的有效测试空间进行了预估。实验结果表明:位于该模拟器双锥中心正下方且距离该中心5.5~7.5 m的测点场的峰值基本按照测点与双锥中心间距的倒数衰减,且随着测点与双锥中心间距的增大,因锥与极板不连续结构导致的波形变化在时间轴上滞后,而因地面影响导致的波形变化在时间轴上提前;在距离地面比较高的水平面上,两极板之间场的外泄方向场的衰减比双锥中轴线方向场的衰减更慢;该模拟器内部距离地面2 m的水平面上12 m×12 m的区域内所取测点的归一化场平均峰值约为0.678,归一化场平均峰值的标准偏差约为0.068 9,场的均匀性约为2.039 dB。
