【Abstract】 A fast sound field calculation method based on Gaussian beam model is proposed. The method based on BELLHOP sound field calculation model can solve Gaussian beam trajectory equation and adjoint equation iteratively by increasing sound velocity profile uniform grid interpolation and boundary layer fast processing steps, and obtain acoustic ray tracing and transmission loss. The method is fast and robust, and it can solve the problems of estimating torpedo homing performance in real time and forecasting sound field of torpedo attack scheme accurately. Simulation shows its correctness and validity.更多还原
