主　　题：shallow water waveguide dispersion curves ocean parameter inversion 

摘      要：The dispersion characteristics of shallow water can be described by the dispersion curves,which contain substantial ocean parameter information.A fast ocean parameter inversion method based on dispersion curves with a single hydrophone is presented in this *** method is achieved through Bayesian *** sets of dispersion curves extracted from measured data are used as the input *** inversion is performed by matching a replica calculated with a dispersion *** bottom characteristics can be described by the bottom reflection phase shift parameter *** propagation range and the depth can be inverted quickly when the seabed parameters are represented by on parameter *** inversion results improve the inversion efficiency of the seabed ***,the inversion efficiency and accuracy are improved while the number of inversion parameters is decreased and the computational speed of replica is *** inversion results have lower error than the reference values,and the dispersion curves calculated with inversion parameters are also in good agreement with extracted curves from measured data;thus,the effectiveness of the inversion method is demonstrated.
