Abstract

Dispositivo sensor de radar para la detección de la distancia y/o de la velocidad de un objeto con relación al dispositivo sensor, con un oscilador (2) sintonizable en la frecuencia, que puede ser activado electrónicamente por medio de una función de modulación (m(t)), para la generación de una señal de emisión (f(t)), una antena de emisión (7, 13) para la emisión de una señal de radar sobre la base de la señal de emisión (f(t)), una antena de recepción (8, 13) para la recepción de la señal de recepción de radar (e(t)) reflejada por el objeto a detectar, una unidad de demodulación (9) para la formación de una señal de medición de recepción demodulada (MESS(t)) a partir de la señal de emisión (f(t)) y de la señal de recepción de radar (e(t)), una unidad de control (1) para el control del dispositivo sensor y para la evaluación de la señal de medición de recepción (MESS(t)), caracterizado por un conmutador de potencia (4) colocado entre el oscilador(2)y la antena de emisión (7, 13), que puedeser activado por una función de control de la potencia (a(t)), para la variación de la potencia de emisión (PHF) de la antena de emisión (7, 13) y, una unidad de referencia (12) asociada al oscilador (2) para la generación de una señal de referencia (r(t)) para la supervisión de la frecuencia y la fase del oscilador (2), donde el dispositivo sensor puede ser accionado por medio de un ajuste variable, realizado por la unidad de control (1), de la función de control de la modulación y de la potencia (m(t) a(t)), de forma alternativa, en al menos dos tipos de funcionamiento diferentes (CW, FM), que se superponen, que están adaptados a diferentes regiones de medición del dispositivo de control.
