摘要：
Traveling wave velocity is the key to the measuring accuracy of the time-domain reflectometry cable length measurement system. The velocity value is affected by many factors. In order to reduce the velocity frequency characteristics impact on time-domain reflectometry cable length measurement system, the effect of frequency on traveling wave velocity is studied, the velocity curve of traveling wave as a function of frequency is established. The traveling wave velocity in coaxial cable as a function of cable length is measured. The experimental results show that the signal frequency is different in different cable lengths because of attenuation and different frequency corresponds to different velocity.
