LARGE-ARRAY SIGNAL AND NOISE ANALYSIS: SEPARATION OF TIME-OVERLAPPING SHORT-PERIOD EVENTS.

Abstract

Techniques for separating short-period time-overlapping events having similar epicenters were studied and, for the two pairs of events used, simple summation was found to be an effective separation technique. The signal-extraction filters which were designed were only partially successful because of problems of exact time-alignment of the signals and because of overdesign of the filter system (due to the short signal gate compared to the number of channels and filter length required). Apparently, the methods could be improved significantly by aligning the signals more exactly and by using substantially fewer channels in the filter design. (Author)
