Channel and cylindrical shell coupling ring array element signal modeling method based on high-order vector decomposition

The invention relates to the technical field of underwater scattering sound field array element signal modeling, in particular to a channel and cylindrical shell coupling circular ring array element signal modeling method based on high-order vector decomposition. Comprising the steps of simulation of acoustic transmission circular ring array element domain signals of an underwater sound field, decomposition of the acoustic transmission circular ring array element domain signals to a high-order vector domain and reduction of the high-order vector domain signals to rigid circular ring array element signals. Acoustic transmission ring array element domain signals in a sound field are obtained through an arbitrary sound propagation model, and then the acoustic transmission ring array element signals are converted into infinite-length rigid cylinder surface ring array element signals in combination with a high-order vector decomposition method. 本发明涉及水下散射声场阵元信号建模技术领域，尤其是一种基于高阶矢量分解的信道与柱壳耦合圆环阵元信号建模方法，包括水声场透声圆环阵元域信号的仿
