瞬变电磁测量中的自适应滤波方法

THE ADAPTIVE FILTERING TECHNIQUE IN THE TRANSIENT ELECTROMAGNETIC MEASUREMENT

    摘要
  • 摘要: 50Hz工频及其谐波干扰对瞬变电磁测量精度的影响十分严重,本文提出了消除50Hz工频及其谐波干扰的自适应滤波及相关-自适应滤波方法,对于提高测量精度非常有效

     

    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.
