Abstract
The estimation of the characteristics of motion of the object controllable by means of seismic monitoring system is considered. It is assumed that the motion in a local area of space is uniform and rectilinear, and the problem is therefore reduced to estimating the coordinates of the initial point and velocity vector. The input data are measured time delay differences in receiving seismic signals by various sensors of the system. Usually, these measurements are formed as a sequential flow in real systems. The obtained estimates of the trajectory also have the form of a sequence, and their accuracy increases with increasing number of primary data. The accuracy of the proposed method are analyzed by statistical simulation.
