Abstract

PROCESO TELEMETRICO PARA MEDIR DISTANCIAS CORTAS POR EMISION CONTINUA MODULADA POR UNA SECUENCIA SEUDOALEATORIA QUE POSEE UN NUMERO N DE BITS EMITIDOS A LA FRECUENCIA DE RELOJ (FH) Y CORRELACION DEL ECO DETECTADO CON LA SEÑAL MODULADA RETARDADA DE MANERA CONOCIDA, SIENDO LA FRECUENCIA DE RELOJ (FH) VARIABLE, EN FUNCION DE LA MEDIDA DE CORRELACION, EN UN CAMPO DE FUNCIONAMIENTO DIVIDIDO EN VARIAS GAMAS DE FUNCIONAMIENTO, PROCESO QUE CONSISTE EN MODIFICAR EL NUMERO N DE BITS DE LA SECUENCIA SEUDOALEATORIA EN FUNCION DE LOS CAMBIOS DE GAMA DE FUNCIONAMIENTO DE LA FRECUENCIA DE RELOJ (FH). APLICACION EN MEDIDAS PROXIMETRICAS POCO ALEJADAS DE UNA SUPERFICIE REFLECTANTE.
