Abstract

The influence factors of underwater acoustic propagation are the basis of underwater acoustics. Considering the characteristic of shallow sea environment, two kinds of typical sound profiles in the WOA05 dataset are chosen for investigation in this paper. Under different restrictions, the characteristics of the two typical sound profiles are analysed contrastively by changing the bottom sediment, the depth of sound source and the frequency of sound source with the application of KRAKEN normal mode model. The influence of different kinds of ocean environment on the imaging of acoustics imaging device underwater is analysed. The simulation results show that the influence degree of sound speed profile by bottom sediment is related to the profile shape and the sound attenuation is reduced with the increase of source depth. Furthermore, the sensitivities of different sound speed profiles to sound frequency were different.
