摘　　要：为解决镜面单锥电场标准装置的时域和频域性能验证问题,深入分析了国内外相关的标准规范和研究现状,提出了一种镜面单锥电场标准装置的时-频域性能验证方法。在时域上,将镜面单锥电场标准装置与TEM室所产生瞬态电磁脉冲电场的脉冲波形参数(幅度、上升时间、脉冲宽度)进行比对;在频域上,将镜面单锥电场标准装置与μTEM室产生的连续波电场强度进行比对,时域和频域性能验证的比对结果均采用En值进行评定。研究镜面单锥电场标准装置的时-频域性能验证方法,突破镜面单锥电场标准装置的时域和频域性能验证难点,对于保证我国脉冲电场量值溯源的准确性,促进我国瞬态脉冲电场参数的量值统一,具有重要意义。This study proposes a method to verify the time domain and frequency domain performance of specular single cone electric field standard devices,drawing on an analysis of relevant international and domestic standards and research.In the time domain,pulse waveform parameters(amplitude,rise time,pulse width)of the transient electromagnetic pulse electric fields generated by both the specular single cone electric field standard device and the TEM chamber are compared.In the frequency domain,the comparison is made between the continuous-wave electric field strengths generated by the specular single cone device and theμTEM chamber.The En value is employed to assess the comparison results in both time and frequency domain performance verifications.This research,focusing on the development of a time-frequency domain performance verification method for specular single cone electric field standard devices,addresses the challenges in verifying both time and frequency domain performances of these devices.It is crucial for ensuring the accuracy of pulse electric field measurements in China and for harmonizing the transient pulse electric field parameters.
