  • 摘要:

    航空电子设备之间的互联线缆是电磁干扰耦合的重要路径。对线缆耦合进行建模分析时,线缆终端共模阻抗是至关重要的输入参数。而航电系统线缆数量较多,提高线缆终端共模阻抗的测试效率,有利于快速建立线缆耦合模型。为此,提出了一种快速测试线缆终端共模阻抗的方法。首先,根据多导体传输线理论证明,在分析共模电流时可以将多芯线缆等效为一根单导体。进而,将线缆束等效为多导体传输线,并采用矢量网络分析仪和电流探头测量各条线缆2个任选位置处的电压反射系数。然后,基于所建立的多导体传输线模型,构造以终端阻抗为未知数的方程组。最后,采用数值迭代算法求解该方程组,得到各条线缆的终端共模阻抗。与现有方法相比,所提方法提高了测试效率和测试精度。
