EFT测试空间辐射特性的仿真及实验验证
Simulation and Experiment Study on Radiated EM Characteristics of
Electrical Fast Transient/Burst Immunity
摘要 在分析电快速瞬变脉冲群干扰信号理论模型的基础上,采用CST 软件建立了相应的仿真模型,提取了不同空间位置的辐射场强,并通过相应实验测得实际测试环境中干扰信号所产生的空间辐射场强。结果表明,实验结果与仿真结果具有一定的吻合性,这说明EFT 测试过程中会在空间产生一定的辐射电磁场。

Abstract In this paper, on the based analysis of the theoretical model of electrical fast
transient, the soft CST is used to establish the simulation model and the radiated field
strength in the different space position is extracted. Then the corresponding
experiment is established to test the radiated field strength produced by the real
interference signal in the different space position. The experiment results are coincided
to the simulation results, which mean that the space radiation electromagnetic field
exists during the EFT testing.
