Sensitivity & resolution

Radiation patterns of the scattering virtual sources: the angular sensitivity behind multiparameter trade-off.

  • Acoustic radiation pattern

    Sensitivity · Acoustic radiation

    Scattered-wavefield snapshots of the partial-derivative virtual sources for the acoustic (Vp, ρ) / (Vp, Iₚ) parameterizations — the angular sensitivity behind multiparameter trade-off. Reproduces Operto et al. (2013) Fig. 2.

  • Elastic radiation pattern

    Sensitivity · Elastic radiation

    Elastic (Vp, Vs, ρ) P-P / P-S / S-S radiation patterns: the analytic Born kernel against sweep's Born-differenced numerics, the δln relative sizes (Vs/Vp ≈ 0.6), and scattered-wavefield snapshots. Cf. Operto Fig. 8(c,d) / Forgues & Lambaré.
