【摘要】 双绞线凭借较好的抗干扰特性在水下自航器中被广泛使用,而水下自航器紧凑而狭小的结构要求其内部大量的线缆成束敷设,这使得线缆串扰问题成为其系统电磁兼容性设计的一个关键考虑因素;采用传输线理论,建立了双绞线电路之间的串扰仿真模型,并进行了试验验证;仿真结果与试验数据具有良好一致性,充分表明传输线模型可有效地完成双绞线串扰预测,可为水下自航器线缆布局的电磁兼容性优化设计提供理论指导。更多还原

【Abstract】 Twisted wires is wildly used in Underwater Autopilot because of its well anti-jamming performance,while the compact and small structure confines the cables lay in bundles,which makes crosstalk between wires in bundles be a key consideration of system-level electromagnetic compatibility design for Underwater Autopilot.Based on transmission-line theory,crosstalk model for twisted wires is presented in this paper and in order to validate the model some experiments are then implemented.The consistency of the experimental data and the simulation data shows that the transmission line model can accurately predict the crosstalk for twisted wires.The model can be used for guiding the EMC design of cable bundles in Underwater Autopilot.更多还原
