Positioning of Microseism in a Rock-Mass on Array Signal Processing

摘要：

Microseismic signal in a rock-mass is detected by the acoustic sensor arrays consisting of multiple array elements and high-resolution DOA estimation of microseismic signal is performed by array signal processing. Positioning of the microseism source is achieved through the intersection of DOA of the twin array; the mathematical model of the microseismic signal array manifold is established; the entire positioning algorithm is simulated. Its feasibility is verified and its precision is very high.
