Abstract
SEGUN EL PROCESO, SE ENVIA AL MEDIO UN HAZ SONORO DE GRAN ABERTURA ANGULAR; SE DETECTAN LAS SEÑALES REFLEJADAS POR EL MEDIO Y RECIBIDAS POR VARIOS TRANSDUCTORES QUE PERTENECEN A UNA RED Y SE MEMORIZA LAS SEÑALES EN FORMA NUMERICA, SE SELECCIONA LOS ECOS QUE PROVIENEN DE UNA ZONA PARTICULAR DE DICHO MEDIO, Y SE LES MEMORIZA; SE DEVUELVEN TEMPORALMENTE LAS NUEVAS SEÑALES REFLEJADAS POR EL MEDIO, Y SE LAS REMITE; SE MEMORIZAN LAS NUEVAS SEÑALES REFLEJADAS Y SE REPITE LA OPERACION DE RETORNO TEMPORAL. DESPUES DE UN ULTIMO RETORNO TEMPORAL DEL ORDEN DE 2N+1 (DONDE N ES UN ENTERO POSITIVO O NULO), SE DETERMINAN LAS CARACTERISTICAS DEL FRENTE DE ONDA QUE PASA LO MAS CERCA DE LA MAXIMA DE LAS SEÑALES.
