强电磁脉冲有效带宽上升时间测量带宽 High-EMP Effective bandwidth Rising time Measurement bandwidth

摘要

从能量分布和测量有效性的观点出发,提出了强电磁脉冲的能量有效带宽和动态范围有效带宽的概念.针对IEC61000-4-4,MIL-STD-464,IEC61000-4-2,IEC61312-1等标准规定的核电磁脉冲(NEMP)、雷电电磁脉冲(LEMP)、静电放电电磁脉冲(ESDEMP)等强电磁脉冲,分别计算了它们的能量有效带宽和动态范围有效带宽.通过分析,得知在一定的范围内,上述强电磁脉冲上升时间的变化对两种有效带宽的影响并不明显,在此基础上,确定了它们的测量带宽.计算结果为NEMP,ESD EMP及LEMP的60 dB有效带宽分别是371,786,1 233 MHz与96 kHz;99%能量有效带宽分别是46,95,183 MHz与15 kHz;不失真测量所需的带宽分别是152,307,916 MHz和95 kHz.

Abstract

The bandwidths of high-electromagnetic pulses generated by high altitude nuclear explosion, lightning and ESD have been investigated. In terms of the energy spectrums of the high-EMP and from the viewpoint of measurement validity, we have put forward two new concepts, energy effective bandwidth and dynamic range effective bandwidth, to represent the bandwidth of the high-EMP. Both of the effective bandwidths of the high-EMP specified in IEC61000-4-4, MIL-STD-464, IEC61312-1 and IEC61000-4-2, have been calculated,60 dB effective bandwidthes are separately 371 MHz, 786 MHz,1 233 MHz,96 kHz and 99% energy effective bandwidthes 46 MHz, 95 MHz, 183 MHz and 15 kHz. In addition, it has been known that the rising time of above high-EMP has a little impact on the two kinds of effective bandwidth, and it is neglectable within a certain range. At last, the measurement bandwidthes of above high-EMP are given,which are separately 152 MHz, 307 MHz, 916 MHz and 95 kHz.
