Abstract
LA INVENCION SE REFIERE A UN SENSOR DOPPLER CON UN GENERADOR (1) DE FRECUENCIA QUE DISPONE DE UNA UNIDAD (2) DE RECEPCION Y TRANSMISION CONECTADA POR MEDIO DE UNA GUIA (12) DE ONDAS Y CON DOS DIODOS (D1, D2) ACTUANDO COMO MEZCLADOR QUE RECIBE LAS SEÑALES EN LA GUIA (12) DE ONDA A INTERVALOS DE UN OCTAVO DE LONGITUD DE ONDA, DE TAL MODO QUE ESTAS SEÑALES NO ESTAN SUPERPUESTAS LINEALMENTE, OBTENIENDOSE SEÑALES DE FASE DESPLAZADA A TRAVES DE 90 IR DE LOS CUALES, MEDIANTE DIFERENCIACION EN UN DIFERENCIADOR (4), SE OBTIENE UNA SEÑAL DE BAJO RUIDO DE FORMA SUFICIENTE, QUE CONTIENE LA DIFERENCIA ENTRE LA FRECUENCIA GENERADA MEDIANTE EL GENERADOR (1) DE FRECUENCIA Y LA FRECUENCIA DE DESPLAZAMIENTO DOPPLER DE LA SEÑAL RECIBIDA Y REFLEJADA COMO UNA FRECUENCIA INTERMEDIA, A PARTIR DE LA CUAL SE DETERMINA LA CANTIDAD DE LA VELOCIDAD RELATIVA A SER MEDIDA EN UNA UNIDAD (5) DE EVALUACION.
