Abstract

LA PRESENTE INVENCION CONCIERNE A UN DISPOSITIVO DE CORRECCION DE UN DESFASE DE FRECUENCIA DEBIDO AL EFECTO DOPPLER EN UN SISTEMA DE TRANSMISION. EL DISPOSITIVO DE CORRECCION DE UN DESFASE DE FRECUENCIA DEBIDO AL EFECTO DOPPLER SE APLICA EN UN SISTEMA DE TRANSMISION EN EL QUE UNA SEÑAL ES TRANSMITIDA EN UN LOBULO DE EMISION ENTRE UN EMISOR (S) Y UN RECEPTOR (R) EN MOVIMIENTO RELATIVO. EL DESFASE DE FRECUENCIA (AF) QUE ES LA DIFERENCIA ENTRE LAS FRECUENCIAS DE LA SEÑAL TRANSMITIDA MEDIDAS EN EL RECEPTOR (FR) Y EN EL EMISOR (FE) SE PRESENTA COMO LA SUMA DE UNA FRECUENCIA CENTRAL (FC) CARACTERISTICA DEL LOBULO DE EMISION Y DE UNA FRECUENCIA DE POSICION (F) FUNCION DE LA POSICION DEL RECEPTOR (R) EN EL LOBULO DE EMISION. EL DISPOSITIVO COMPRENDE UNOS MEDIOS PARA SINTONIZAR EL RECEPTOR (R) QUE PRESENTA UNA FRECUENCIA DE SINTONIZACION (FA) DE MODO QUE ESTA FRECUENCIA DE SINTONIZACION (FA) SEA IGUAL A LA SUMA DE LA FRECUENCIA EMITIDA (FE) Y DE LA FRECUENCIA CENTRAL (FC).
