Abstract
(EN) Disclosed in the present invention are a Butler matrix-based phase weighting optimization method and a Butler matrix capable of realizing the method. The method is based on an n×n order Butler matrix, wherein n=2N, and N is a positive integer. The method comprises: respectively providing an adjustable phase shifter at each input port; n input signals respectively passing through the corresponding input ports and the corresponding adjustable phase shifters, and then performing N-stage vector synthesis, and n output beams being outputted from n output ports; obtaining, for any one output beam, a phase difference theoretical value and a phase difference actual value between two input signals for vector synthesis in each stage of vector synthesis, so as to obtain a phase difference error value between the two input signals; and according to the phase difference error value, respectively calculating and adjusting the amount of adjustment required by each adjustable phase shifter. By means of the Butler matrix-based phase weighting optimization method of the present invention, phase deviation of a Butler matrix can be reduced, and beam synthesis performance of the Butler matrix is improved.
(FR) La présente invention concerne un procédé d'optimisation de pondération de phase basé sur une matrice de Butler, et une matrice de Butler permettant de réaliser le procédé. Le procédé est basé sur une matrice de Butler d'ordre n × n, avec n = 2N, N étant un entier positif. Le procédé comprend les étapes consistant à : disposer respectivement un déphaseur réglable au niveau de chaque port d'entrée ; faire passer n signaux d'entrée respectivement à travers les ports d'entrée correspondants et les déphaseurs réglables correspondants, puis effectuer une synthèse vectorielle en N étapes, et délivrer n faisceaux de sortie par n ports de sortie ; obtenir, pour tout faisceau de sortie, une valeur théorique de différence de phase et une valeur réelle de différence de phase entre deux signaux d'entrée pour la synthèse vectorielle à chaque étape de synthèse vectorielle, de manière à obtenir une valeur d'erreur de différence de phase entre les deux signaux d'entrée ; et en fonction de la valeur d'erreur de différence de phase, calculer et ajuster respectivement la quantité d'ajustement requise par chaque déphaseur réglable. Au moyen du procédé d'optimisation de pondération de phase basé sur une matrice de Butler de la présente invention, un écart de phase d'une matrice de Butler peut être réduit, et les performances de synthèse de faisceau de la matrice de Butler sont améliorées.
(ZH) 本发明公开了一种巴特勒矩阵相位加权优化方法及可以实现该方法的巴特勒矩阵,该方法基于n×n阶巴特勒矩阵,其中n=2N,N为正整数,包括:在每个输入端口处分别设置一个可调移相器;n个输入信号分别经过对应的输入端口和对应的可调移相器后,进行N级矢量合成,并从n个输出端口处输出n个输出波束;获取对于任意一个输出波束,在每一级矢量合成中进行矢量合成的两个输入信号之间的相位差理论值和相位差实际值,进而获得两个输入信号之间的相位差误差值;根据相位差误差值,分别计算每个可调移相器所需的调节量并进行调节。根据本发明的巴特勒矩阵相位加权优化方法,能够降低巴特勒矩阵的相位偏差,提高巴特勒矩阵波束合成性能。
