Tomographic wavelet estimation via higher order statistics

Research output: Contribution to conference › Paper › peer-review

Abstract

Efficient estimation of nonminimum-phase (NMP) ARMA wavelets is a very important part of seismic deconvolution. "Phase-blind," autocorrelation-based approaches, used up to now, are restricted to minimum-phase (MP) wavelets. In this paper we develop two methods for NMP wavelet identification. We model the reflectivity sequence as a non-Gaussian, stationary and independent random process (rp). The estimated wavelet best fits the amplitude sensitive autocorrelation sequence and a phase-sensitive higher order statistics sequence of the (perhaps noisy) seismogram. The parameter estimates are consistent and robust with respect to additive Gaussian white noise. We test our methods and compare them with existing NMP wavelet estimation techniques, using synthetic examples.
