【Abstract】 The optimization algorithms have significant effect on inverting the underwater acoustical parameters.Matched field inversion is conducted by using a hybrid method which combines the global genetic algorithms and the local Levenberg-Marquardt method.The combination of a global and a local method makes the inversion faster and results in a state closer to the global minimum.The inversion analysis based on simulated data and experimental data shows that the hybrid method works better compared with the individual global methods.更多还原
