中文摘要: |
根据三天线法的原理,提出了用三电缆线法来校正信号传输中由于电缆线的移动、弯曲或老化引起的电缆线传输特性的变化.该方法将三条电缆线两两组合成三对,进行三次连续的测量,从而得出电缆线的传输特性和校正因子,对测得的信号进行校正.该方法对传输信号而非反射信号的测量,克服了电缆线损耗引起的对交换反射计的使用限制. |
英文摘要: |
Based on the three-antenna method, the three-cable method has been devised to be applied to correcting for variations in cable transfer characteristic due to motion, flexure or aging. The method is to measure the cable in transmission and to infer the characteristic of the cable from a set of three pairwise measurements and get the correction factor to correct the measured data. By measuring in transmission, rather than in reflection, it overcomes the limitation imposed by cable loss on the use of the switched reflectometer. |
