Synyavskyy and all // Радиоэлектроника и информатика : науч.-техн. журн. – Х. : Изд-во ХНУРЭ, 2008. – Вып. 4. – С. 49-56.http://openarchive.nure.ua/handle/document/1848The principles of spectral estimation are investigated in this paper to develop a common approach to the solution of both localization problem of spatiallydistributed electromagnetic sources and identification problem of multilayer structures. The process of experimental data registration in a linear antenna array and multi-frequency means of multilayer structure non-destructive evaluation is described by proposed identical models. The order and parameters of the models are determined by mean of stochastic approach to the spectral estimation, which allows to obtain higher spectral resolution and accuracy in case of low signal to noise ratio.endirection of arrival estimationmaximum likelihoodArticle
