Abstract

In most of the existing impact point positioning methods based on seismic wave, the velocity of seismic wave needs to be inversed or measured in advance, which causes a large positioning error. An impact point positioning method based on objective function is proposed. The unknown parameters of objective function are only the coordinates of the impact point, so there is no need to measure the wave velocity in advance or inverse the wave velocity. The simplex method is used to optimize the objective function, and the density-based spatial clustering of applications with noise (DBSCAN) algorithm is used to locate the impact point.The method can effectively suppress the positioning error caused by uneven wave velocity. A simulation model is esatablished to verify the feasibility of the positioning algorithm. When the positioning method is applied to the ground static explosion experiment and the data obtained by the geophone is used to locate the explosion center, the relative positioning error is 0.38%, which proves the correctness of the positioning method.
