Abstract:

Two features of the ILLIAC IV system at NASAAmes are particularly appropriate to the processing of seismic data. One is its ability to apply a given algorithm to sixty-four different data streams simultaneously, thus providing an order of magnitude increase in processing speed over conventional machines. The second is its large data storage. The seismological algorithms for convolution filtering, beamforming, matched filtering, PHILTRE, maximum likelihood, and FKCOMB are each able to take advantage of these features in the processing of seismic data. The data can be arranged so that each processing element contains successive time windows on a given trace, as in bandpass filtering, or successive beam sets, as in beamforming.
