Bayesian full‐wavefield reflection coefficient inversion and uncertainty estimation

摘要: This paper presents a Bayesian inversion technique to recover seabed geoacoustic properties of multi‐layered media from measured broadband reflection‐loss data taking full‐wavefield effects into account. Seismo‐acoustic traces are time windowed packets with reflection different sets layers increasing depth. Each packet is processed yield coefficients as function angle and frequency. The coefficient inverted using forward model. posterior probability density sampled Gibbs sampler that steps through the packages, results for one package prior knowledge constrain subsequent inversions. Prior about number their thicknesses obtained separate picked travel times. final considered full solution inverse problem interpreted in terms parameter estimates, marginal ...
