Study of Source Location Error by Computer Simulation.

摘要

The location of sources of waves propagating with unknown speed above (electromagnetic,infrasonic,acoustic-gravity wave) or below (seismic wave) the surface of the earth may be deduced from time-of-arrival measurements made at four synchronized stations. In order to determine how errors in arrival time relate to errors in source location and signal velocity, a computational procedure was developed. The latter is aimed at finding the optimum network configuration for determining the most probable source location and velocity of a propagating signal from given errors of time-of-arrival measurements.
