| Abstract: | For layered ocean models,a new method of numerical simulation is presented on the basis of the theory of smooth-averaged sound field.By this method the averaged sound field in layered ocean can be calculated easier and faster.The IFP (Image Field Program)and SFP (Smooth-average Field Program) used for calculating the sound intensities at short and long ranges,respectively,are developed.At intermediate ranges,both IFP and SFP may be used,and the sound intensities calculated by IFP and SFP are well coiacident.The above-mentioaed method may be utilized for more extensive types of velocity-profile and boundary-reflection-loss,and used for predicting sound field. |
