Bayesian Inversion for Geoacoustic Parameters in Shallow Sea
TL;DR: Inversion results of the experimental data are in good agreement with both measured values and estimates from Genetic Algorithm inversion result in the same environment, and results indicate that the sound speed and density in the seabed have fewer uncertainties and are more sensitive to acoustic pressure than thesound speed attenuation.

Bayesian geoacoustic parameters inversion for multi-layer seabed in shallow sea using underwater acoustic field
TL;DR: In this paper , an inversion method based on Bayesian theory is presented to derive the structure and geoacoustic parameters of a layered seabed in a shallow sea, where the authors considered a layered elastic medium.

A Method for Inverting Shallow Sea Acoustic Parameters Based on the Backward Feedback Neural Network Model
TL;DR: In this paper , a shallow water acoustic parameters inversion method based on a feedback (BP) neural network model is proposed, where the theoretically predicted values of the shallow water sound pressure field are obtained through the fast field method (FFM).

Inversion of shallow seabed structure and geoacoustic parameters with waveguide characteristic impedance based on Bayesian approach
TL;DR: In this article , a nonlinear Bayesian theory is used to invert the above geoacoustic parameters and analysis the uncertainty of the inversion results, which can accurately represent the seabed characteristics in the experimental sea area.
