摘要：
A three-dimensional analytical solution is constructed for the model of an inhomogeneous hydroacoustic waveguide with a cylindrical inhomogeneity within the sedimentary layer. A numerical-analytical method for finding the velocity potential is proposed, for which undefined coefficients for normal modes are determined from the corresponding infinite system of linear algebraic equations. The asymptotic behavior of the amplitude coefficients in the system is investigated. Sound fields with variation of the parameters of the problem are numerically studied.
