Resolution analysis in full waveform inversion (2011, methodology): “…methodology is the design of objective functionals, commonly constructed to meet criteria in the data space, such as robustness (Crase et al. 1990; Brossier et al. 2010) and separation of phase and amplitude (Luo & Schuster 1991; Gee & Jordan 1992; Fichtner et al. 2008; Bozdağ et al. 2011).”
AxiSEM: broadband 3-D seismic wavefields in axisymmetric media (2014, background): “Most modern measurements of “traveltimes”, such as cross-correlation (Nolet, 2008), time–frequency phase delays (Fichtner et al., 2008), or instantaneous phase (Bozdag et al., 2011) are based on waveforms, and therefore necessitate full wavefield modeling.”
Seismic imaging: From classical to adjoint tomography (2012, background): “, 2011a), and other frequency-dependent functionals such as those based on short-time Fourier transform (Fichtner et al., 2008), or generalized seismological data functional (Chen, 2011).”
Multiscale adjoint waveform tomography for surface and body waves (2015, background): “Reducing the nonlinearity of waveform inversion problems involves a judicious choice of the objective function (Luo and Schuster , 1991; Gee and Jordan, 1992; Dahlen and Baig, 2002; Fichtner et al., 2008; Bozdağ et al., 2011; Rickers et al., 2012; Masoni et al., 2014).”
Full Waveform Inversion and the Truncated Newton Method (2013, methodology): “Cross-correlation of observed and synthetic data [38], comparison of the instantaneous phase and envelope of the signals [19, 7], deconvolution approaches where Wiener filters are used to match observed and predicted data [37, 77, 80], and image-domain techniques [72] are all instances of these atte”
