An antenna array and signal preprocessing apparatus and method. The antenna array is a quadrature polarized array having two orthogonal electric dipoles (30) and two orthogonal magnetic dipoles (40). The preprocessor is for preprocessing signals from the antenna, for obtaining spatial spectrum information for signal source location. The preprocessor comprises an autocorrelator, connected after said input, for forming signal autocorrelation matrices for each element, and an smoother, connected after said autocorrelator, for averaging said autocorrelation matrices, thereby to form a sample covariance matrix suitable for use in a Eigenstructure based estimator for estimating source localization.

L'invention concerne un réseau d'antennes ainsi qu'un appareil et un procédé de prétraitement de signaux. Ledit réseau d'antennes est un réseau polarisé en quadrature possédant deux doublets électriques orthogonaux et deux doublets magnétiques orthogonaux. Le préprocesseur est conçu pour le prétraitement de signaux provenant de l'antenne, en vue de l'obtention d'informations relatives au spectre spatial pour la localisation de source de signaux. Le préprocesseur comprend un auto-corrélateur, connecté après ladite entrée, pour la formation de matrices d'auto-corrélation de signaux pour chaque élément, et un lisseur, connecté après ledit auto-corrélateur, pour assurer le moyennage desdites matrices d'auto-corrélation, et former ainsi une matrice de covariance d'échantillon convenant à l'utilisation dans un estimateur fondé sur une structure propre pour l'estimation de la localisation de sources.
