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。
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 correlativeadaptive filtering techniques used to remove the 50Hz operating ferquency and its harmonic disturbance,it is very effective to increase the measurement accuracy.
