摘要 采用变步长切线法来判定脉冲在时域反射仪(简称TDR)探针上的传输时间,并通过程序实现了该方法的自动判定过程,完成介电常数的自动计算。最后将时域反射仪TDR-I系统所采集的数据对该方法进行测试,效果良好。 Travel time of pulse on TDR probe is determined with a variable-step tangent algorithm. A program is also designed to determine travel time and evaluate the permittivity automatically according to the algorithm. An good effect is accomplished by testing data sampling by TDR- I system.
