The model of phase distribution was analyzed,it was demonstrated that symmetrically tuning the free-running frequency of the boundary oscillators in circular array,a linear phase distribution could be achieved with the steady working frequency of array unchanged.
从阵列独立单元的非线性动力学方程出发,建立了该相位阵的连续相位数学模型,分析了阵列相位分布函数,对称地调节圆域边界振荡器的自由谐振频率时,阵列的稳定工作频率不变,相位在阵列中实现了线性分布,加上辐射单元后该圆形阵列可用于空间波束扫描。
This model was used to find that tuning the free-running frequency of oscillators could achieve linear phase distribution for phase-shifterless beam s.
