Localization of the wideband sources with estimation of the antenna shape

Abstract : The purpose of this paper is the passive angular location of the wideband sources using an array of sensors. The interest of the knowledge of the antenna shape, when the treatment is applied on the received data, is illustrated by the improvement of the signal to noise ratio and the increase in antenna directivity. In this paper, the extension of the propagator method is presented: an algebraic operator is extracted from the cross-spectral matrices of the data or from the received signals. This technique avoids the rather expensive eigendecomposition of cross-spectral matrices at each frequency of the analysis bandwidth used in the known methods. The results of simulations support the theoretical predictions.
