高空核爆电磁脉冲波形标准及特征分析
High altitude nuclear electromagnetic pulse waveform standards: a review
-
摘要: 目前，国际上已有美军标、国际电工委员会、Bell实验室及各种学术出版物等各种高空核爆电磁脉冲波形标准。综述了这些标准，并从时域参数、频谱、归一化累积能流谱、总的能量密度等几方面研究其异同性。比较后认为，IEC61000-2-9和MIL-STD-461E表述的新标准要比1976年出版物波形和Bell实验室波形的频谱范围宽，对电子系统的小孔缝耦合效应稍强，但对多数效应物尤其是线缆引入的传导耦合，损伤程度则相对弱化。最后，分析了由于HEMP波形表述形式变化，给EMP模拟器和效应研究带来的影响和新动态趋势。Abstract: There are a number of high altitude nuclear electromagnetic pulse (HEMP) waveform standards for equipment and systems on susceptibility to the testing effects. These typical HEMP standards include IEC6100029, MILSTD461E and some other publication standards such as Bell Laboratory's etc. The time domain parameters, amplitude spectrum, and the cumulative energy fluence of these HEMP waveforms are compared in this paper. The results show that earlytime HEMP in IEC6100029(equals to MILSTD461E) is less severe than HEMP in the 'publication 1976' and Bell laboratory standard except for slots coupling as the former have slightly shorter rise time and more wide 3dB bandwidth. In the end, the influence on the HEMP simulation and effects due to the change of HEMP standard are also
