Abstract
LA INVENCION SE REFIERE A ANTENAS LINEALES COMPUESTAS POR DETECTORES (H,{SUB,1} A H{SU,N} CON DIRECTIVIDAD OMNIDIRECCIONAL Y UNA ANTENA AUXILIAR (AG, AD) CON DIRECTIVIDAD EN FORMA DE CARDIOIDE QUE SE UTILIZA PARA LEVANTAR LA AMBIGUEDAD DERECHA/IZQUIERDA DE LA ANTENA PRINCIPAL. A ESTE EFECTO, SE CALCULA LA COHERENCIA (34) ENTRE LAS SEÑALES QUE PROCEDEN DE LA ANTENA PRINCIPAL CON CADA UNA DE LAS SEÑALES D({SUB,T}DE LAS DOS VIAS DERECHA E IZQUIERDA DE LA ANTENA AUXILIAR, LO QUE PERMITE POR COMPARACION DE LOS DOS VALORES DE COHERENCIA LEVANTAR LA AMBIGUEDAD. APLICACION EN LAS ANTENAS REMOLCADAS.
