摘要： Disclosed in the present invention is a method for suppressing airborne transient electromagnetic in-band vibration noise, comprising: dividing the data after current turn-off into two segments according to whether the useful signal is attenuated to the system noise level: the segment A is the useful signal segment, and the segment B is the pure noise segment; limiting the bandwidth of the data of the segment B according to the frequency range of the in-band noise, and labeling the result as BL; training a neural network using the BL, utilizing the well trained neural network to predict the in-band vibration noise contained in the data of the segment A, and labeling the prediction result as PNA; and subtracting the PNA from the data of the segment A to suppress the in-band vibration noise contained in the data of the segment A.
