Abstract: The article deals with the problem of determining the origin of the sound source in a information redundancy conditions. This problem arises at spatial localization of a source of a sound by group of the mobile robots equipped with binaural systems of technical hearing. The paper discusses two approaches to solving this problem: the formulation of necessary conditions of an extremum of square functional and then solving of the received non-linear system of the equations and numerical methods of the gradient minimization. The paper presents the results of numerical studies based on these two approaches.
Keywords: group of mobile robots, coordinates of sound source, information redundancy, Newton’s method, steepest descent method
