NEW APPROACH TO SEISMIC-REFLECTION EVENT DETECTION AND VELOCITY DETERMINATION

Recently a number of high-resolution techniques for event detection and parameter estimation (velocity) have emerged in the field of multichannel sonar array processing. We find that a practical and computationally efficient implementation of these methods is possible for seismic reflection data. This implementation results in development of the covariance measure for event detection and velocity estimation in seismic reflection data. The measure is based on the eigen-structure of the sampled data covariance matrix. Computer implementation of the covariance measure provides a high resolution method for determination of velocity spectra relative to currently used techniques. -from Authors
