Abstract

UN METODO DE EXPLORAR OBJETOS MEDIANTE ECOGRAFIA ULTRASONICA.LAS SEN/ALES RECIBIDAS SE REPARTEN O DIVIDEN EN CIERTO NUMERO (N) DE BANDAS DE FRECUENCIA CONSECUTIVAS Y DE APROXIMADAMENTE IGUAL ANCHURA, QUE EN SU CONJUNTO ABARCAN APROXIMADAMENTE TODAS LAS FRECUENCIAS DE LAS SEN/ALES RECIBIDAS. SE DETERMINAN LA ENVOLVENTE DE LAS SEN/ALES DE CADA BANDA DE FRECUENCIA, Y CADA UNA DE LAS ENVOLVENTES SE MULTIPLICA POR UNA SEN/AL DE CORRECCION A FIN DE COMPENSAR EL EFECTO DE DIFRACCION. SE DETERMINA EL LOGARITMO DE LAS ENVOLVENTES ASI CORREGIDAS, DESPUES DE LO CUAL SE EFECTUAN LAS SIGUIENTES OPERACIONES POR MEDIO DE LAS N SEN/ALES ASI OBTENIDAS: (A) SE DETERMINA LA PENDIENTE BBBFRL DE CADA UNA DE ESTAS N SEN/ALES; (B) ESTA SEN/AL BBBFRL SE CONVIERTE A LA FORMA LOGARITIMA; (C) EN UNA TABLA O EN UNA CURVA SE FIJA LA RELACION ENTRE EL VALOR LOGARITMICO DE LA FRECUENCIA PARA CADA CANAL (LOG FI) Y EL VALOR LOGARITIMO (LOG BBBFRL) DETERMINADO EN LA OPERACION (B); Y (D) SE DETERMIAN LA PENDIENTE DE LA CURVAASI OBTENIDA Y EL VALOR DE LOG BBBFR PARA LOG F F O.
