Abstract:

The effectiveness of the iterative beaming technique for the separation of superposed Rayleigh wave signals was evaluated. This technique can be useful for the detection and discrimination of seismic events the signals of which arrive simultaneously at a seismic array. The technique was applied to superposed recordings of Rayleigh waves at LASA. It was found the multipathing of Rayleigh waves can cause enough leakage into the beam of the desired event to make the separation impossible if the amplitude of waves from the event to be eliminated is more than three times that of the event of interest.
