摘要: 分析了实验室瞬态X射线产生的系统电磁脉冲(SGEMP)效应测试所面临的技术问题，提出了解决方法、措施以及实验室模拟瞬态X射线的SGEMP模拟试验方法。通过电子屏蔽、电磁屏蔽、光电隔离、信号对称提取等特殊技术处理，解决了SGEMP效应模拟试验方法和测量系统抗X射线、抗电磁辐射等技术问题，并在大型瞬态X射线模拟源上，测出了瞬态X射线辐照时金属腔内线缆的SGEMP效应波形及幅值。Abstract: Analysis of technical problem is presented on the laboratory experimental simulation techniques on the system generated electromagnetic pulse (SGEMP) effects of transient X-ray. And a new method for effective measurement of the SGEMP effects and the experimental simulation method of SGEMP effects to transient -ray are proposed. By certain designs, such as electrons shield, electromagnetism shield, photo-electricity insulation, and signal symmetrical process, X-ray hardness and anti-electromagnetic interference are solved in the measurement system. Under the irradiation of a large scale transient pulse X-ray simulation source, the measurement system can measure fairly good waveforms of SGEMP effects of the cables.
