Accurate Method for Picking Up the First Arrival Time of Microseismic Signals Based on Entropy Theory
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 result...
