中文摘要：
从设计和研制实际测试系统的角度出发,对电磁脉冲的不失真测试带宽进行了分析和讨论。在分析电磁脉冲时频域特征的基础上,利用典型的二阶低通和高通滤波器传递函数模型,分别研究了测试系统中上、下限截止频率以及系统阻尼比对电磁脉冲波形参数的影响,并给出了一种在时域利用电磁脉冲波形参数误差来近似评估带限测试系统不失真测试带宽的方法,通过获得测试系统的-3dB带宽和阻尼比等参数设置,可用于指导实际测试系统的设计和研制。
英文摘要：
In view of design and development of the actually measurement system,the undistorted measurement bandwidth of electromagnetic pulse（EMP） is analyzed and discussed in this paper.On the basis of analyzing characteristics of the EMP in time and frequency domains,typical 2-order low-pass and high-pass filter models are utilized to analyze the EMP waveform parameters and its distortion affected by the low cut-off and high cut-off frequency of the band-limited system respectively.A method to evaluate the undistorted measurement bandwidth by computing errors of the EMP waveform parameters in time-domain was proposed.By using this method,the-3dB bandwidth and damping ratio of the measurement system can be calculated,and the results can be used for guiding design and develop the actually measurement system.
