A mathematical model for localization of acoustical sources with separation between them is derived and presented. A classical ( Fourier transform ) method and a modern ,parametric , ( Burg ) method are used . The results show the capability of Burg method to resolve the adjacent sources when compared with Fourier transform method, as well as the localization of the sources . The performance is studies with varying some parameters relating to the problem.
