Abstract

Un sistema autónomo de procesamiento de señales acústicas (50), que comprende: un conformador de haces verticales (60) acoplado para recibir una pluralidad de señales de hidrófonos a partirde una pluralidad correspondiente de hidrófonos sensibles al sonido en el agua, donde el conformador dehaces verticales (60) está configurado para conformar una pluralidad de señales de haces de recepciónverticales, siendo la pluralidad de señales de haces de recepción verticales representativa de una pluralidadrespectiva de haces de recepción acústicos no direccionales en acimut y direccionales en elevación; un conformador de haces acimutales (70) acoplado para recibir la pluralidad de señales de haces de recepciónverticales y configurado para conformar una pluralidad de señales de haces de recepción direccionales, siendola pluralidad de señales de haces de recepción direccionales representativa de una respectiva pluralidad dehaces de recepción acústicos direccionales en acimut y direccionales en elevación; un módulo de detección de diana ruidosa (78) acoplado para recibir la pluralidad de señales de haces derecepción direccionales y configurado para generar detecciones y para determinar las direcciones de una omás dianas ruidosas asociadas con la pluralidad de señales de haces de recepción direccionales; y un módulo de matriz (84) acoplado para recibir la pluralidad de señales de haces de recepción verticales,acoplado para recibir las detecciones de la una o más dianas ruidosas, acoplado para recibir las direcciones dela una o más dianas ruidosas, configurado para generar una matriz de covarianza de acuerdo con la pluralidadde señales de haces de recepción verticales, caracterizado por que dicho módulo de matriz está configuradoademás para generar una matriz de covarianza modificada colocando dos fuentes ruidosas sintéticas en ocerca de una dirección angular de una diana ruidosa detectada de acuerdo con las detecciones y direccionesde las dianas ruidosas, por lo que la anchura de nulo de una señal de recepción de haces direccionales dirigidahacia la diana ruidosa es ajustable.
