Review of calculation methods for low-frequency acoustic transmission loss of underwater vehicle in complex marine environments
This paper reviews the traditional methods and improved methods of low-frequency acoustic feature propagation loss calculation of underwater vehicles at home and abroad,and analyzes the applicability of propagation loss simulation calculation in complex marine boundary conditions and three-dimensional marine environment,and extracts and summarizes the research status of propagation loss calculation methods in complex marine environments.In the future,the research on acoustic propagation loss of underwater vehicles will focus more on the characteristics of low-frequency acous-tic propagation,the spatiotemporal-frequency coherence characteristics of the sound field,and the sound propagation law in the polar ice environment,and further improve the accuracy and stability of the propagation loss calculation method in com-plex marine environment.
