Short summary
The technique of microseismic source location is realized by calculating the time difference of arrival estimation of each mocroseismic signal. The time difference of arrival estimation directly affects the accuracy of microseismic source location. Microseismic signal with noises is proved to be closer to the α-stable distribution in this paper, and an improved time difference of arrival estimation approach microseismic signals is proposed.
