RI 7626 A Least Squares Method For Improving The Source Location Of Rock Noise

The least squares method of rock noise source location presented is shown to be more accurate and reliable than standard direct solution methods. This method is particularly effective in improving solutions from rock noise locations outside of geophone array boundaries. A least squares solution for a medium .in which the seismic velocity is the same in all directions is also presented. In this special case, one can solve for both the source coordinates and the velocity.
