基于现有标准中没有专门用于测试辐射式核电磁模拟器场均匀区域方法的现状,通过搭建辐射式核电磁脉冲模拟器试验系统并进行试验测试和数据分析,明确了辐射式模拟器的场均匀区域应在近场区内以脉冲峰值为标准进行定义,在均匀区域内只考虑脉冲峰值的变化;脉冲峰值随距离呈线性变化;在距离平面上的场分布具有一定规律,因此提出通过测试距天线口径面3m位置起3个点的场值来获得场均匀区域的方法。使用该方法测得辐射式核电磁脉冲模拟器场均匀区域为4.5m(长)×6m(宽)×6m(高),为下一步开展电磁脉冲效应试验提供了前提条件。
Based on the fact that there is no specific method for testing the uniform field of radiant nuclear magnetic simulator field in the existing standards, a radiant nuclear magnetic pulse simulator test system is set up, and the test and data analysis are conducted. The field of the radial simulator The uniform region should be defined in the near-field region as the peak value of the pulse. Only the change of the pulse peak is considered in the homogeneous region. The peak value of the pulse changes linearly with the distance. The field distribution in the distance plane has certain rules. Therefore, The distance from the antenna aperture 3m position 3 points from the field value to obtain a uniform field method. Using this method, the uniform field of radiant nuclear electromagnetic pulse simulator is 4.5m (length) × 6m (width) × 6m (height), which provides the precondition for the next electromagnetic pulse experiment.
