Digital seismic inverse methods

Book ·
OSTI ID:6306412

This mathematically based text presents the basic geophysical models used today. It is designed as a text or reference information for courses in geophysics, and also as a professional reference. It presents following contents; the seismic method as a communication system, the design of high-resolution digital filters; principles of digital wiener filtering; sampling geophysical data, filter theory and wave propagation; random processes; spectral estimation; predictive decomposition of seismic traces; multichannel z-transforms and minimum delay; the spectral function of a layered system and the determination of waveforms at depth; deconvolution; spectral approach to geophysical inversion by Lorentz, Fourier, and radon transforms; dynamic predictive deconvolution; the normal incidence synthetic seismogram; maximum entropy and the relationship of the partial autocorrelation to the reflection coefficients of a layered system; maximum entropy spectral decomposition of a seismogram into its minimum entropy component plus noise; optimum stacking techniques; optimum digital filters for signal-to-noise ratio enhancement; bibliography, and index.
