以对称三角形耦合振荡器阵列为本振阵列,分析了耦合本振振荡器的相位控制原理,推导了耦合本振稳定同步形成均匀的平面相位分布,且反对称地调节边界单元的自由振荡频率,可改变本振信号的线性相位分布,确定了加权矢量,得出波束形成方向图,并通过仿真验证了三角形耦合本振阵列天线阵接收波束形成的可行性。

In this paper, the local oscillator arrays were presented using the symmetry triangle coupled oscillator arrays, and its phase control principle was analyzed. It was deduced that the phase distributing was symmetrical when coupled-LO arrays was synchronized, and the phase step between coupled-LO array units only had relation with the boundary oscillators frequency. According this attribute the weight vector was derived, and the beamforming directional diagram was obtained. Thought, it was validated that the beamforming of antenna arrays using triangle coupled local oscillators was feasible.
