Abstract:

This report addresses the problem of estimating the parameters of superimposed signals observed by an array of sensors. Some of the proposed techniques are equally useful for estimating the frequencies of sinusoids in noise. The methods used are direct iterative maximum likelihood, the EM algorithm, the eigenstructure approach and the polynomial approach. In addition to the traditional estimation of the source locations we also address the estimation of parameters related to the radiation patterns of the sources.
