Abstract: 通过研究阶跃电压信号因电缆的阻抗变化而引起的的反射规律 ,推导出了在多个强间断变化阻抗的情况下 ,阻抗的相对变化量与反射电压的关系 ,以及同轴电缆几何尺寸变化与电缆传输阻抗之间的关系 .指出在小变形的假设下 ,它们之间存在着理想的线性关系 .同时 ,举例说明了同轴电缆的时域反射技术在交通工程中的应用
The time domain reflectometry of the coaxial cable was analyzed by studying the relation between the cable geometry and the characteristic impedance as well as the relation between the change of characteristic impedance and the voltage of reflected wave. The linearity was derived from the relations when the small deformation condition was applied. Finally, an application of TDR in the traffic engineering was presented.
