Deployment method of graphic processor for scattering transfer function of underwater targets
In order to improve the calculation speed of broadband echoes of underwater targets,this paper proposes a solution for fast computation of the scattering transfer function at multiple frequency points based on graphics processing unit(GPU).Compared to the traditional approach of calculating each frequency point individually,the CUDA fast algorithm fully utilizes the relative independence of target intensity at different frequency points and takes advantage of the hardware characteristics of GPUs to simultaneously compute the scattering sound field within the broadband,significantly improving the computational efficiency.The cylindrical model is used as a case study in this paper to compare and analyze the calcula-tion speed under different grid quantities.The simulation results demonstrate that,compared to traditional CPU serial compu-tation,utilizing the CUDA fast algorithm can achieve an acceleration ratio of over 80,effectively improving the calcula-tion speed.
