Abstract:

An iterative beam processor is developed which in the limit is identical to the mixed-signal processor Dean et. al., 1968. Assuming that two events arrive simultaneously at an array consisting of N sensors, the array is first beamed on one of the two epicenters to produce a signal estimate for this event 0th iteration. This signal estimate is then time-shifted and subtracted from each of the original N seismograms in an attempt to remove the signal from the original seismograms. The new set of records, each containing N stripped seismograms, is then beamed to produce a signal estimate for the second event.
