Abstract

G. V. Alekseev as well recent papers [2, 4] where the first results of theoretical study of acoustic nonlinear inverse source problems are presented for the model case when D = R 2 or D = R3 respectively. Finally, we note papers [5-8] devoted to numerical study of linear and nonlinear inverse source problems of underwater acoustics when D is a regular oceanic waveguide in R2 or R3 unbounded in horizontal directions and bounded vertically. In this paper we are concerned with theoretical study of acoustic nonlinear inverse source problems for an unbounded domain D C R3 with a reflecting boundary S which models an oceanic wavegiude. We consider two problems. The first one (Problem 2.1) consists in finding an unknown radiating system geometry (a simply connected domain ft C -D), given the distribution of the source density and the outer potential of the radiated field. Problem 2.2 consists in finding a radiating system that generates such an additional acoustic field which minimizes (or suppresses) the primary sound field, created by a noising object, over some subdomain Q of the domain D.
