| 目的 研究毫米波引信近炸探测器超宽带(Ultra-wideband，UWB)电磁脉冲防护加固措施，提高引信的电磁防护能力。方法 利用超宽带辐照试验平台，开展辐照试验，通过测试，确定受损探测器的损伤部位，明确辐照效应机理，并提出针对性加固措施。结果 超宽带电磁脉冲可使探测器出现死机或硬损伤的现象，受试探测器的效应场强阈值在50~80 kV/m。死机可在重启后恢复，而硬损伤为不可恢复现象。结论 毫米波引信近炸探测器对超宽带电磁脉冲较为敏感，锁相环回路是探测器的敏感部位。探测器暴露在辐照场下的射频电路和天线窗口是超宽带能量的主要耦合通道。采取改进元器件布局、更换器件和屏蔽线等加固措施后，探测器超宽带的防护能力有较大提升，证明了加固措施的有效性。 |

| The paper aims to improve the electromagnetic protection capability of the fuze and study the reinforcement measures of ultra-wideband electromagnetic pulse protection for the proximity detector of the millimeter wave fuze. The ultra-wideband irradiation test platform is used to carry out the irradiation test, through which the damaged part of the damaged detector is determined, the irradiation effect mechanism is clarified, and targeted reinforcement measures are proposed. The ultra-wideband electromagnetic pulse can cause the detector to crash or hard damage, and the threshold of the effect field strength of the detector under test is between 50 kV/m and 80 kV/m. A crash can be recovered after a restart, while hard damage is unrecoverable. The millimeter wave fuze proximity detector is sensitive to ultra-wideband electromagnetic pulses, and the phase-locked loop is the sensitive part of the detector. The RF circuit and antenna window of the detector exposed to the radiation field are the main coupling channels of the ultra-wideband energy. After the reinforcement measures such as improving the layout of components and replacing components and shielding wires, the ultra-wideband protection capability of the detector is greatly improved, which proves the effectiveness of the reinforcement measures. |
