Estimation of Separation and Location of Wave Emitting Sources : A Comparison Study between Parametric and Non-parametric Methods

摘要

A mathematical model for localization of acoustical sources with separation between them is derived andpresented. 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 withFourier transform method, as well as the localization of the sources . The performance is studies withvarying some parameters relating to the problem .
