ABSTRACT

An analytical-numerical algorithm is suggested for the analysis of a hydroacoustic waveguide with its parameters essentially variable along its path. When developing the solution, we accounted for the possibility to decompose the waveguide’s domain into elementary subdomains where the velocity potential can be written as a sum of normal waves with undetermined coefficients. An infinite system of linear algebraic equations was obtained to found these coefficients. Examples of numerical calculations are presented. A satisfactory compliance of the results with experimental data is shown.
