Summary:The present invention relates to a cylindrical array radar. In particular, the cylindrical array radar comprises: a ring array in which a plurality of transmission/reception modules for transmitting and receiving high-frequency signals in the radar frequency band are arranged in a circular shape, and a ring array signal processing unit for processing signal data exchanged with the plurality of transmission/reception modules is disposed in the center of the arrangement of the transmission/reception modules; and a main signal processing unit which performs antenna beamforming of the plurality of transmission/reception modules and performs signal processing for detecting and tracking a target. Thus, the cylindrical array radar can detect in all antenna directions without mechanical rotation, and has the effect of facilitating performance change. La présente invention concerne un radar à réseau cylindrique. En particulier, le radar à réseau cylindrique comprend : un réseau circulaire dans lequel une pluralité de modules d'émission/de réception destinés à émettre et recevoir des signaux haute fréquence dans la bande de fréquence radar sont disposés selon une forme circulaire, et une unité de traitement de signal de réseau circulaire destinée à traiter des données de signal échangées avec la pluralité de modules d'émission/de réception est disposée au centre de l'arrangement des modules d'émission/de réception ; et une unité de traitement de signal principale qui effectue une formation de faisceau d'antenne de la pluralité de modules d'émission/de réception et effectue un traitement de signal pour détecter et suivre une cible. Ainsi, le radar à réseau cylindrique peut détecter dans toutes les directions d'antenne sans rotation mécanique, et a pour effet de faciliter un changement de performances. 본 발명은 원통형 어레이 레이더에 관한 것으로서, 특히 레이더 주파수 대역의 고주파 신호를 송수신하는 다수의 송수신 모듈이 원형으로 배열되고, 상기 다수의 송수신 모듈과 주고받는 신호 데이터를 처리하는 링 어레이 신호처리부가 송수신 모듈의 배열 중심부에 배치된 링 어레이와; 상기 다수의 송수신 모듈의 안테나 빔포밍을 수행하며, 표적을 탐지하고 추적하는 신호처리를 하는 메인 신호처리부;를 포함하여 구성되어, 기계적 회전 없이도 안테나 전(全)방향을 탐지할 수 있고, 성능 변경을 용이하게 할 수 있는 효과가 있다.
