Abstract

La invención se refiere a un detector por radar FMCW que comprende una pluralidad de módulos de alta frecuencia (10, 12), los cuales se sincronizan uno con otro mediante una señal de sincronización (sync), y de los cuales al menos uno tiene una parte transmisora (16) para generar una señal de transmisión de frecuencia modulada (TX), y de los cuales al menos dos módulos de alta frecuencia (10, 12) físicamente separados uno de otro comprenden respectivamente una parte receptora (20) para recibir un eco de radar (E), siendo a que cada parte receptora (20) se le asigna un mezclador (22) que genera una señal de frecuencia intermedia (Z1, Z2) mediante la mezcla de la señal recibida (RX) con una porción de la señal transmitida (TX), y una unidad de evaluación (24, 34), y siendo que la unidad de evaluación (24, 34) se configura para registrar la señal de frecuencia intermedia (Z1, Z2) durante un período de medición como una función del tiempo y someter la señal de tiempo (S1, S2) obtenida de esta manera a una transformación de Fourier, caracterizado porque al menos una (34) de las unidades de evaluación se configura para ventanear la señal de tiempo (S1) previamente a la transformación de Fourier con una señal de ventana (V) de valor complejo con el fin de compensar una diferencia de tiempo de propagación de la señal de sincronización (sync) entre las partes receptoras (20).
