Abstract

APARATO PARA CODIFICAR INFORMACION DE IMAGEN DE LOCALIZADOR DE CARDUMENES (BANCOS DE PECES) Y METODO DE TRANSMISION. LAS SEÑALES ANALOGICAS DE INFORMACION DE CARDUMEN SON CONVERTIDAS SUCESIVAMENTE DE FORMA ANALOGICA A DIGITAL. LAS SEÑALES TAMBIEN SON CONVERTIDAS EN SEÑALES PULSATORIAS DE CARDUMEN, DIVIDIDAS SOBRE LA BASE DE UN IMPULSO PERIODICO DE SINCRONISMO Y SUMADAS. LOS DATOS DE INFORMACION DE CARDUMEN SON MUESTREADOS A INTERVALOS PREDETERMINADOS PARA UNA PLURALIDAD DE AMPLITUDES DE SEÑALES UNIDAD DETERMINADAS POR LA BASE DE TIEMPO. LOS DATOS SON ORDENADOS CON UNIDADES DE BIT Y ALMACENADOS EN LA MEMORIA. LAS SEÑALES MUESTREADAS SON CONVERTIDAS EN CODIGO MORSE Y LAS SEÑALES EN CODIGO MORSE SON TRANSMITIDAS CON SEÑALES DE SINCRONISMO CORRESPONDIENTES A LAS SEÑALES UNIDAD. LA ANCHURA DE BANDA RESULTANTE DE TRANSMISION ES MAS ESTRECHA QUE EN EL SISTEMA CONVENCIONAL DE TRANSMISION DE IMAGEN Y REDUCE LA INFLUENCIA DEL RUIDO CUANDO LAS DISTANCIAS DE TRANSMISION SON GRANDES.
