弹上电缆抗干扰仿真分析

Simulation Analysis of Anti-interference of Cables on Missile

弹上电缆是弹上所有信息的传输通路,也是电磁干扰的主要耦合通道。首先,对弹上电缆间相互干扰以及外部电磁脉冲辐射对弹上电缆的干扰进行了仿真,分析了电缆排布因素对线缆间相互干扰的影响以及电磁脉冲不同极化方式、入射角度对弹上电缆的干扰等;随后,运用仿真技术对弹上电缆进行电磁兼容性仿真分析,可以快速观察各个设备的受扰情况,为导弹抗干扰设计提供可靠的依据。

The cable on missile is the transmission path of all the information on the missile,and also the main coupling channel of electromagnetic interference.The interference between the cables on the missile and interference of external electromagnetic pulse radiation on cables are simulated in the paper.Influence of cable arrangement factors on mutual interference between cables,interference of electromagnetic pulse with different polarization modes and incidence angle on the cables are analyzed.The simulation analysis of the electromagnetic compatibility of cables on missile can be used to quickly observe the disturbance of each device and provide a reliable basis for the design of missile anti-jamming.
