Coupled Oscillators Array with Arbitrary Interconnection Topology and Its Application in Conformal Phased Array

摘要:

提出了一种利用耦合振荡器阵列实现共形相控阵天线波束扫描的新方法。建立了任意拓扑结构的耦合振荡器阵列幅度和相位动力学方程,采用图论的方法分析了稳态相位方程解的唯一存在性和稳定性,通过控制振荡器每个单元的自由振荡频率,对相位进行加权,实现了共形相控阵天线无移相器的波束扫描,最后对圆柱形耦合振荡器阵列天线进行了数值仿真,验证了该方法的可行性。

Abstract:

A new beam-canning technique of conformal phased array by coupled oscillators array was presented. The amplitude and phase dynamic equations of coupled oscillators array with arbitrary interconnection topology were provided, then the existence and stability of steady phase distribution were analyzed with graph theory. It was shown that a phase-shifterless beam-scanning could be achieved with phase weighting by tuning the free-running frequency of each oscillator in array. A column form coupled oscillator’s array antenna was simulated to verify its feasibility.
