Title (EN) ANTENNA DEVICE AND METHOD FOR REDUCING GRATING LOBE
(FR) DISPOSITIF D'ANTENNE ET PROCÉDÉ DE RÉDUCTION DE LOBE SECONDAIRE D'ANTENNE RÉSEAU
(JA) アンテナ装置及びグレーティングローブの低減方法
Abstract:
(EN) A signal synthesis unit (33) specifies, from a gain in a grating lobe direction in a first radiation pattern and a gain in the grating lobe direction in a second radiation pattern, a weighting factor w by which grating lobe included in a synthesized signal S3 of a digital received signal S1 and a digital received signal S2 that are stored in a signal calculation/storage unit (31) is suppressed when the digital received signals are synthesized, and using the weighting factor w, synthesizes the digital received signal S1 and the digital received signal S2 that are stored in the signal calculation/storage unit (31).
(FR) Selon l'invention, une unité de synthèse de signaux (33) spécifie, à partir d'un gain dans une direction de lobe secondaire d'antenne réseau dans un premier diagramme de rayonnement et d'un gain dans la direction de lobe secondaire d'antenne réseau dans un second diagramme de rayonnement, un facteur de pondération w par lequel un lobe secondaire d'antenne réseau compris dans un signal synthétisé S3 d'un signal reçu numérique S1 et d'un signal reçu numérique S2 qui sont stockés dans une unité de calcul/stockage de signaux (31) est supprimé lorsque les signaux reçus numériques sont synthétisés, et à l'aide du facteur de pondération w, synthétise le signal reçu numérique S1 et le signal reçu numérique S2 qui sont stockés dans l'unité de calcul/stockage de signaux (31).
(JA) 信号合成部(33)が、第1の放射パターンでのグレーティングローブ方向の利得と、第2の放射パターンでのグレーティングローブ方向の利得とから、信号算出記憶部(31)により記憶されているディジタル受信信号Sとディジタル受信信号Sを合成したときに、その合成信号Sに含まれるグレーティングローブを抑圧する重み係数wを特定し、その重み係数wを用いて、信号算出記憶部(31)により記憶されているディジタル受信信号Sとディジタル受信信号Sを合成する。
