The harmonic retrieval (HR) problem concerns the estimation of the frequencies in a sum of real or complex harmonics. Both correlation and cumulant-based approaches are used for this purpose. Cumulant-based HR algorithms use a single 1-D slice of the

Propagator and wave-equation inversion for near-receiver material properties

Autor: R. van Vossen, Jeannot Trampert, Andrew Curtis

Publikováno v: van Vossen, R, Trampert, J & Curtis, A 2004, ' Propagator and wave-equation inversion for near-receiver material properties ', Geophysical Journal International, vol. 157, no. 2, pp. 796-812 . https://doi.org/10.1111/j.1365-246X.2004.02249.x

SUMMARY Near-receiver material properties are required for the separation of the recorded wavefield into upgoing and downgoing P and S waves, and are also important for static time-shift corrections. However, it is difficult, especially in land seism

A DATA-DRIVEN CORRECTION OF ULTRASONIC SOURCE AND RECEIVER SPECTRAL AMPLITUDE VARIATIONS

Autor: P. J. S. van Capel, R. van Vossen, A. W. F. Volker, Donald O. Thompson, Dale E. Chimenti

Publikováno v: AIP Conference Proceedings.

The application of phased arrays in NDT applications is growing. State of the art ultrasonic arrays consist of many small piezo-electric elements that can be excited separately to synthesize a desired wave front. This may vary from simple plane waves

A Simple and Accurate Formula for the Absorption of Sound in Seawater

Autor: R. van Vossen, Michael A. Ainslie, C.A.M. van Moll

Publikováno v: IEEE Journal of Oceanic Engineering, October, 4, 34, 610-616

In this communication, a new empirical formula for the absorption of sound in seawater is derived. The starting point of this investigation is the formula proposed by Ainslie and McColm for attenuation due to the boron and magnesium relaxations. Cons

Surface-consistent amplitude corrections for single or multicomponent sources and receivers using reciprocity and waveform inversion

Autor: R. van Vossen, Andrew Curtis, Jeannot Trampert

Publikováno v: Van Vossen, R, Curtis, A & Trampert, J 2006, ' Surface-consistent amplitude corrections for single or multicomponent sources and receivers using reciprocity and waveform inversion ', Geophysical Journal International, vol. 165, no. 1, pp. 311-322 . https://doi.org/10.1111/j.1365-246X.2006.02908.x

SUMMARY In land seismics, near-surface conditions often vary within surveys, resulting in differences in source strength and signature. Furthermore, discrepancies between closely spaced recordings are also commonly observed. Processing and interpreta
