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。In this paper, on the based analysis of the theoretical model of electrical fasl transient, the soft CST is used to establish the simulation model and the radiated field strength in the different space position is extraeled. Then the corresponding experiment is established to test the radiated field strength pr^dueed by the real inlerferenee signal in the differenl space position. The experiment results are coincided to the simulation results,which mean thai the space radiation eleetromagnelie field exists during the EFT testing.
