Method of extracting weak signals from strong disturbance field in coal mineral well based on wavelet transform

Disturbance fields in the coal mineral well give a so serious problem on the work of general electric investigation that sometime process of observing useful signal cannot be finished. For extracting weak effective signals from strong disturbance field in coal mineral well, original measured signals are decomposed by wavelet transform and Mallet algorithm, and the weak effective signals are extracted successfully. Experimental results show that the approach method is feasible and efficient.
