Abstract
UN DETECTOR DE PROXIMIDAD A UN OBSTACULO EN UN VEHICULO EN LA FORMA DE UN APARATO DE RADAR CON EFECTO DOPPLER DIPLEX PROVEE UN RANGO DE INFORMACION ENTRE UN VEHICULO Y EL OBSTACULO SOBRE LA BASE DE UN CORRIMIENTO DE FASE ENTRE UN PAR DE SEÑALES DOPPLER (D1, D2) DERIVADAS DE DOS SEÑALES TRANSMITIDAS POR RADAR A FRECUENCIAS LIGERAMENTE DISTINTAS. UN ERROR QUE DEPENDE DE LA VELOCIDAD ES INTRODUCIDO MEDIANTE UNA CONSTANTE DE TIEMPO DE UN CIRCUITO DE FILTRO (54) QUE CONVIERTE LA INFORMACION DE LA GAMA DEL CICLO DE SERVICIO EN UN CORRIMIENTO DE FASE A UNA SEÑAL ANALOGICA COMPENSADA POR LA INTRODUCCION DE UN PEQUEÑO CORRIMIENTO DE TIEMPO (35) EN EL RECORRIDO DE LA SEÑAL DE UNA DE LAS SEÑALES DOPPLER PARA REALIZAR UN CORRIMIENTO EN LA INFORMACION DE LA GAMA DEL CICLO DE SERVICIO.
