Abstract:

The two commonly used sources in the multi-transient electromagnetic (MTEM) method, square-wave and m-sequence, have different anti-noise performance which had been theoretically discussed in previous studies. But the onshore contrast experiment had rarely been conducted. An onshore experiment was performed over the Laizhou gold deposite, China, and the results obtained with two different source signatures were compared and analyzed. The signals had the same amplitude similar to 40 A and about the same length, so they had approximately equal energy. Two data sets with extremely different signal-to-noise ratio (SNR) were acquired with different source-receiver offsets. The skin-depth of two sources was analyzed; the recovered earth impulse responses indicated that m-sequence can compensate the high-frequency attenuation handsomely and the powerline noise suppression of m-sequence is 22 dB greater than the suppression of the square-wave, which demonstrated the superiority of m-sequence in MTEM data processing.
