传统的二维互注入锁相耦合振荡器阵列采用矩形栅格结构,可以实现无移相器的波束形成和扫描.矩形结构阵列相邻阵元相位差限制在[?90°,90°]内,当阵元间距为半波长时,其水平和俯仰波束扫描范围限制在偏离法线方向30°以内.论文提出了一种菱形结构的二维耦合振荡器阵列,给出了其相位控制方法,并对相位控制误差进行了分析.在对菱形结构的耦合振荡器阵列的稳定性进行分析后,给出了稳定条件,对阵列的稳定过程和相位控制方法进行了计算机仿真,对理论分析结果进行了验证.该菱形结构耦合振荡器阵列,在水平和俯仰方向上相邻阵元的相位差可达[-180°,180°],具有比矩形栅格结构更宽的波束扫描范围.
The traditional two-dimensional mutual injection lock-coupled oscillator array uses a rectangular grid structure, which can realize the beamforming and scanning without phase shifter.The phase difference of the adjacent array elements of the rectangular structure array is limited within [? 90 °, 90 °] , When the array element spacing is half wavelength, the horizontal and pitch beam scanning range is limited within 30 ° from the normal direction.This paper presents a diamond-shaped two-dimensional coupled oscillator array, and gives the phase control method, And the phase control error is analyzed.After analyzing the stability of the diamond resonator coupled oscillator array, the stability conditions are given, the stability of the array and the phase control method are simulated by computer, and the theoretical analysis results are carried out The rhombus structure-coupled oscillator array has a phase difference of [-180 °, 180 °] between adjacent elements in the horizontal and pitch directions, and has a wider beam scanning range than the rectangular grid structure.
