摘　　要：为研究高功率微波武器通过雷达外露电缆后门攻击雷达系统可能造成的毁伤问题,建立了雷达单元间电缆模型。对比分析不同电缆类型、架设高度、电场方向、电缆长度对耦合信号的影响;通过辐照实验测量耦合信号特征,分析耦合信号对雷达的影响;设计相应的防护电路,并讨论其他的防护措施。理论分析和实验结果表明,耦合信号峰值电压和波形受电缆型号、架设高度、电场方向等因素影响较大;耦合信号谐振频率受电缆长度影响较大。通过技术防护措施和合理布设电缆的方法可降低耦合信号威胁。To investigate the potential damage caused by High-Power Microwave Weapons(HPMW)attacking radar systems through exposed cable backdoors,a cable model between radar units is established.The effects of different cable types,installation heights,electric field directions,and cable lengths on coupling signals are compared and analyzed.The characteristics of coupling signals are measured through irradiation experiments,and the impact of coupling signals on radar is analyzed.Corresponding protective circuits are designed,and other protective measures are discussed.Theoretical analysis and experimental results indicate that the peak voltage and waveform of the coupled signal are greatly affected by factors such as cable type,installation height,and electric field direction,while the resonant frequency of the coupled signal is greatly affected by cable length.The threat of coupling signals can be reduced through technical protection measures and reasonable cable layout.
