Title (EN) NOISE MEASUREMENT IN A RADAR SYSTEM
(FR) MESURE DE BRUIT DANS UN SYSTÈME RADAR
Abstract:
(EN) A radar system (180) includes a transmitter (181) including a power amplifier (PA) (184) for amplifying a local oscillator (LO) signal (200), to generate an amplified signal (202). The radar system (180) also includes a receiver (218) including: an IQ generator (182) for generating an I signal (210) based on the LO signal (200) and for generating a Q signal (208) based on the LO signal (200); and a low noise amplifier (LNA) (188) for amplifying a looped back signal (204), to generate a receiver signal (206). The receiver (218) also includes: a first mixer (192) for mixing the receiver signal (206) and the I signal (210), to generate a baseband I signal (212); and a second mixer (190) for mixing the receiver signal (206) and the Q signal (208), to generate a baseband Q signal (214). Also, the radar system (180) includes a waveguide loopback (186) for guiding the amplified signal (202) from the transmitter (181) to the receiver (218) as the looped back signal (204).
(FR) La présente invention concerne un système radar (180) qui comprend un émetteur (181) comprenant un amplificateur de puissance (PA) (184) pour amplifier un signal d’oscillateur local (LO) (200), pour générer un signal amplifié (202). Le système radar (180) comprend en outre un récepteur (218) comprenant : un générateur IQ (182) pour générer un signal I (210) sur la base du signal LO (200) et pour générer un signal Q (208) sur la base du signal LO (200) ; et un amplificateur à bruit faible (LNA) (188) pour amplifier un signal de retour de boucle (204), pour générer un signal de récepteur (206). Le récepteur (218) comprend en outre : un premier mélangeur (192) pour mélanger le signal de récepteur (206) et le signal I (210), afin de générer un signal I de bande de base (212) ; et un deuxième mélangeur (190) pour mélanger le signal de récepteur (206) et le signal Q (208), afin de générer un signal Q de bande de base (214). En outre, le système radar (180) comprend un bouclage de guide d’ondes (186) pour guider le signal amplifié (202) de l’émetteur (181) vers le récepteur (218) en tant que signal de retour de boucle (204).
