| 摘 要： | 车载通信对抗系统具有大功率干扰、高灵敏度接收、对抗设备与通信设备共存、设备集成度高等特点。为解决系统的电磁兼容(Electromagnetic Compatibility,EMC)问题,针对车载通信对抗系统电磁干扰(Electromagnetic Interfer-ence,EMI)的6种传播路径进行了分析。在系统EMC解决方案中,分别从接地设计、电缆屏蔽设计、整机屏蔽设计、电源滤波、电磁频谱规划和天线隔离等方面,通过理论分析及相应的计算方法,给出了具体的系统电磁兼容解决措施,这些措施在工程实践上得到验证,能够有效指导系统的电磁兼容设计。

| Abstract: | The vehicle-mounted communication countermeasure system has the characteristics of high-power jamming,high sensitivity receiving,high integration and coexistence of countermeasure equipment and communication equipment.The six transmission paths of electromagnetic interference of the vehicle-mounted communication countermeasure system are analyzed in order to solve the problem of system EMC.Design of grounding,cable shielding and machine shielding,and aspects of power filter,electromagnetic spectrum planning and antenna isolation are considered in the solutions of system EMC.The measures of system EMC are given by theory analysis and corresponding calculation method.The measures are tested in the engineering practice and can guide the design of system EMC effectively. |
