Abstract EN
The entropy method describes the change in the signal state from a macroscopic angle and weakens the interference generated by random noise.
From the angle of chaos, which describes the first arrival of microseismic signals, it predicts the trend of noise entropy based on the grey theory.
The results indicate that the entropy method is sensitive to amplitude, frequency, and seismic phase changes.
Compared with traditional methods, the entropy method has better noise immunity.
In terms of the influence of the pickup parameter on the resulting error, the entropy method demonstrated the best result and produces the smallest error.
