THE ADAPTIVE FILTERING TECHNIQUE IN THE TRANSIENT ELECTROMAGNETIC MEASUREMENT

    Graphical Abstract
    • Abstract
  • The 50 Hz operating frequency and its harmonic disturbance has a serious influence on the accuracy of transient electromagnetic measurement.The paper presents the adaptive filtering and correlative-adaptive filtering techniques used to remove the 50Hz operating ferquency and its harmonic disturbance,it is very effective to increase the measurement accuracy.
