Abstract:
(EN) Provided is a radar system (1) having a receiver array antenna (20), wherein a signal processing device (30) comprises: a receiver unit (21) which mixes a plurality of received signals and some transmission signals and generates a plurality of beat signals; a domain converter unit (31) which converts the plurality of beat signals into a plurality of frequency domain signals; an all-domain search unit (32) which calculates a first integrated signal by integrating the plurality of frequency domain signals, and detects first target information (Di) on the basis of the first integrated signal; a limited-domain search unit (33) which generates a plurality of phase shift signals by shifting the phases of the plurality of frequency domain signals in order to limit the target detection area to a specified direction of the domain, calculates a second integrated signal by integrating the plurality of phase shift signals, and detects second target information (Dj) on the basis of the second integration signal; and an information output unit (34) which outputs at least one of the first target information (Di) and the second target information (Dj).
(FR) L'invention concerne un système radar (1) ayant une antenne réseau de récepteur (20), où un dispositif de traitement de signal (30) comprend : une unité de réception (21) qui mélange une pluralité de signaux reçus et certains signaux de transmission et qui génère une pluralité de signaux de battement ; une unité de convertisseur de domaine (31) qui convertit la pluralité de signaux de battement en une pluralité de signaux de domaine de fréquence ; une unité de recherche tout domaine (32) qui calcule un premier signal intégré par intégration de la pluralité de signaux de domaine de fréquence, et qui détecte des premières informations cibles (Di) en fonction du premier signal intégré ; une unité de recherche de domaine limité (33) qui génère une pluralité de signaux de décalage de phase par décalage des phases de la pluralité de signaux de domaine de fréquence afin de limiter la zone de détection cible à une direction spécifiée du domaine, qui calcule un second signal intégré par intégration de la pluralité de signaux de décalage de phase, et qui détecte des secondes informations cibles (Dj) en fonction du second signal d'intégration ; et une unité de sortie d'informations (34) qui délivre en sortie les premières informations cibles (Di) et/ou les secondes informations cibles (Dj).
(JA) 受信アレイアンテナ(20)を有するレーダシステム(1)において、信号処理装置(30)は、複数の受信信号と送信信号の一部とを混合して複数のビート信号を生成する受信部(21)と、複数のビート信号を複数の周波数領域信号に変換する領域変換部(31)と、当該複数の周波数領域信号を積分することで第1の積分信号を算出し、当該第1の積分信号に基づいて第1の目標情報(Di)を検出する全域探索部(32)と、当該複数の周波数領域信号の位相を、特定方位の領域に目標検出範囲を限定させるようにシフトすることにより複数の位相シフト信号を生成し、当該複数の位相シフト信号を積分することにより第2の積分信号を算出し、当該第2の積分信号に基づいて第2の目標情報(Dj)を検出する限定域探索部(33)と、第1の目標情報(Di)及び第2の目標情報(Dj)のうちの少なくとも一方を出力する情報出力部(34)とを備える。
