摘要: 讨论了集成光学电场探头测量高空电磁脉冲（HEMP）的系统误差。根据探测器传输函数和HEMP的表达式得出了误差方程。并通过对HEMP表达式的特征分析,对误差方程进行了简化。通过方程的求解,分析了探测器和HEMP波形的各项参数对测量结果的影响。结果表明：误差随着双指数波幅值、半宽/前沿和探测器工作点漂移的增大而增大；探测器的5%和10%系统测量误差对应的最大测量幅值分别为半波电场的0.165倍和0.23倍。该结论可为此类探测器的使用提供参考。Abstract: This paper discusses system error of integrated optical E-field sensors when measuring high altitude electromagnetic pulse (HEMP). Based on the transfer function of detector and the expression of HEMP, the equations of system error are given. Through analysis of HEMP, the error equations get simplified. And the measurement results influenced by the parameters of the detector and the waveform are analyzed. The results show that the system error increases with the amplitude, full width at half maximum amplitude/rise time and the bias drift and the maximum measurement amplitude is 0.165 times of the half wave electric field and 0.23 times of the half wave electric field when the system error is 5% and 10%. The conclusion can provide a reference for this kind of detectors.
