Abstract
(EN)
A radar (300) and a target detection method, for use in improving the anti-jamming capability of a radar under strong suppression jamming. The radar (300) comprises: a receiving module (310), a gain control module (320), and a target position determining module (330) connected in sequence. The receiving module (310) is used for receiving a first signal. The gain control module (320) is used for: measuring the power of the first signal; and if the power of the first signal is greater than or equal to a set threshold, determining that the first signal is a signal transmitted by a target object, attenuating the first signal to obtain a second signal, and outputting the second signal, wherein the power of the second signal is less than the set threshold, and the set threshold is less than or equal to the maximum power of signals that the radar (300) can process. The target position determining module (330) is used for determining first position information of the target object according to the second signal and position information of the radar (300).

La présente invention concerne un radar (300) et un procédé de détection de cible, destinés à être utilisés pour améliorer la capacité d'anti-brouillage d'un radar sous fort brouillage de suppression. Le radar (300) comprend : un module de réception (310), un module de commande de gain (320) et un module de détermination de position de cible (330) connectés en séquence. Le module de réception (310) sert à recevoir un premier signal. Le module de commande de gain (320) sert à : mesurer la puissance du premier signal; et, si la puissance du premier signal est supérieure ou égale à un seuil défini, déterminer que le premier signal est un signal émis par un objet cible, atténuer le premier signal pour obtenir un second signal et délivrer en sortie le second signal, la puissance du second signal étant inférieure au seuil défini et le seuil défini étant inférieur ou égal à la puissance maximale des signaux que le radar (300) peut traiter. Le module de détermination de position de cible (330) sert à déterminer des premières informations de position de l'objet cible en fonction du second signal et des informations de position du radar (300).
