Pour gérer des signaux cohérents avec des angles d'arrivée inconnus, une méthode de formation de faisceau adaptative est proposée et peut être appliquée à un réseau arbitraire. La méthode proposée résout efficacement un problème de valeurs propres généralisé pour estimer les angles d'arrivée du groupe de signaux cohérent souhaité, en exploitant la méthode de Brent en conjonction avec une maximisation alternée. Nous discutons de la condition pour une estimation correcte de la direction sans prendre par erreur des estimations de direction d'interférence pour celles souhaitées. Les résultats de la simulation montrent que les performances du formateur de faisceau proposé sont très similaires à celles du formateur de faisceau avec le vecteur de direction composite (CSV) exact.

Abstract: To handle coherent signals with unknown arrival angles, an adaptive beamforming method is proposed which can be applied to an arbitrary array. The proposed method efficiently solves a generalized eigenvalue problem to estimate the arrival angles of the desired coherent signal group, by exploiting the Brent method in conjunction with alternating maximization. We discuss the condition for the correct direction estimation without erroneously taking interference direction estimates for the desired ones. Simulation results show that the performance of the proposed beamformer is very similar to that of the beamformer with the exact composite steering vector (CSV).
