Abstract

METODO Y APARATO PARA LA PROSPECCION DE ALTA RESOLUCION DEL FONDO DEL MAR, EN EL QUE SE SITUA EN EL AGUA, UN TRANSDUCTOR PARABOLOIDE ELECTROACUSTICO (P1-P10), CUYOS ELECTRODOS ESTAN CERCA DEL FOCO DEL PARABOLOIDE Y ESTAN CONECTADOS AMBOS A UN BANCO CAPACITADOR (C1-C10) CUYA CAPACITANCIA SE PUEDE VARIAR A VOLUNTAD Y A UN CIRCUITO DE SUMINISTRO (G) PARA GENERAR UNA DESCARGA ELECTROACUSTICA ENTRE DICHOS ELECTRODOS. CUANDO LA CAPACITANCIA VARIA, EL TIEMPO DE RETARDO ENTRE EL IMPULSO PRINCIPAL O IMPULSO DE PROSPECCION BAJO EL AGUA Y EL IMPULSO DE CAVITACION ES GRABADO EN CUALQUIER DESCARGA, Y AL MISMO TIEMPO SE DETERMINA LA FRECUENCIA DOMINANTE DEL ESPECTRO DE LA SEÑAL DE PROSPECCION. DESPUES SE FIJAN LOS VALORES DE CAPACITANCIA PARA PROPORCIONAR IMPULSOS DE CAVITACION CUYA CONTRIBUCION AL IMPULSO RESULTANTE ES MINIMA Y EL ESPECTRO DE FRECUENCIA DOMINANTE ES LO MAS AMPLIO POSIBLE. LOS VALORES DE CAPACITANCIA PREFIJADOS SE ASIGNAN A UNA RED DE CAPACITADOR (C1-C10) CONECTADO CADA UNO A UN TRANSDUCTOR PARABOIDAL ELECTROACUSTICO (P1-P10) SUMERGIDO EN AGUA, CUYOS ELECTRODOS SE SUMINISTRAN PARA GENERAR EL IMPULSO DE PROSPECCION BAJO EL AGUA.
