Abstract

In this article approach at the numerical solution of the return problem of acoustics is considered by method of iterations of Landveber. The considered approach consists in the following: for restoration of unknown coefficient in the differential equation we have statement of a direct problem and additional information on the solution of a direct problem. We write out functionality nonviscous, we receive statement of the interfaced problem. Further by means of solutions of a straight line and the interfaced problem we receive a functionality gradient nonviscous [1]. Then for the numerical solution of the return problem from statement of a direct problem we pass to a problem which we will solve on the computer in number.
