Abstract

In this article there is considered a new approach for Active Sources Localization (ASL) based on the measured or given data of the field's distribution on some surface. The task belongs to the solution of the inverse scattering problem based on the Method of Auxiliary Sources (MAS). Inherently, proposed approach is using fundamental property of the scattered field the uniqueness of the wave field's analytical continuation along and backwards its propagation. In the paper we discuss about two approaches for solution state problem. The positions of the active source are determined by means of the converging and diverging wave's function. The program package is created based on both approach and the numerical experiments are realized. The results of simulation show the efficiency of this new proposal.
