Abstract
(EN)
The present invention effectively suppresses the level of an interference signal from another radar unit with respect to the level of a received signal of a radar unit, and avoids increasing the measurement time and the number of additional circuits required for the suppression. A first radar transmission unit transmits a first radar transmission signal periodically with a first transmission period under the control of a first transmission code control unit on the basis of a first transmission trigger signal generated after a first delay time from the reception of a predetermined synchronization establishment signal by a first transmission trigger signal generation unit. A second radar transmission unit transmits a second radar transmission signal periodically with a second transmission period under the control of a second transmission code control unit on the basis of a second transmission trigger signal generated after a second delay time from the reception of the synchronization establishment signal by a second transmission trigger signal generation unit. The arrival times of interference signals from the first radar transmission unit and the second radar transmission unit fall within the respective transmission intervals of the second radar transmission signal and the first radar transmission signal according to the first delay time and the second delay time.

La présente invention réduit efficacement le niveau d'un signal d'interférence à partir d'une autre unité de radar vis-à-vis du niveau d'un signal reçu d'une unité de radar, et évite l'augmentation du temps de mesure et le nombre de circuits additionnels requis pour la réduction. Une première unité d'émission de radar émet un premier signal d'émission de radar de façon périodique avec une première période d'émission sous la commande d'une première unité de commande de code d'émission sur la base d'un premier signal de déclenchement d'émission généré après un premier temps de retard à partir de la réception d'un signal d'établissement de synchronisation prédéterminé par une première unité de génération de signal de déclenchement d'émission. Une seconde unité d'émission de radar émet un second signal d'émission de radar de façon périodique avec une seconde période d'émission sous la commande d'une seconde unité de commande de code d'émission sur la base d'un second signal de déclenchement d'émission généré après un second temps de retard à partir de la réception du signal d'établissement de synchronisation par une seconde unité de génération de signal de déclenchement d'émission. Les temps d'arrivée de signaux d'interférence à partir de la première unité d'émission de radar et de la seconde unité d'émission de radar rentrent à l'intérieur des intervalles d'émission respectifs du second signal d'émission de radar et du premier signal d'émission de radar en fonction du premier temps de retard et du second temps de retard.
