平行双线BCI等效替代强场连续波电磁辐射实验研究

由于互联系统信号传输的基础是双线，以低频线缆耦合通道中比较典型的平行双线为研究对象，针对互联系统单端为非线性受试设备的电磁辐射敏感度进行实验研究。讨论了典型互联系统辐射与注入的等效以及在高场强下的外推条件，对所选非线性器件是否满足实验要求进行了实验验证。分析了大电流注入法等效替代强场连续波电磁辐射的实验结果，并对辐照时天线极化方式不同以及有无大电流注入探头对辐射与注入等效研究的影响进行了分析。

Testing technology of using bulk current injection with parallel double line as substitute for high field continuous wave electromagnetic radiation

Since the signal transmission of the interconnected system is based on two lines, this paper takes the parallel two lines as the research object, which is relatively typical in the low frequency cable coupling channel. Experiments were carried out to study the electromagnetic radiation sensitivity of the equipment whose single end of the interconnected system is non-linear. The radiation and injection equivalence of typical interconnected systems and the extrapolation conditions under high field strength are discussed. The experimental verification of whether the selected nonlinear devices meet the experimental requirements is carried out. The experimental results of using bulk current injection as equivalent substitute for strong field continuous wave electromagnetic radiation are analyzed. And the effects of different polarization modes of the antenna and the presence or absence of the large current injection probe on the equivalence research of radiation and injection are also analyzed.
