A Least Squares Method for Improving Rock Noise Source Location Techniques.
NTIS: PB 209 540 :19 pages
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 bounndaries. 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.
