| 摘 要： | 提出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,给出耦合本振阵列相位控制方法,推导了耦合本振阵列锁相同步时,形成均匀的线性相位分布,且阵元间的相移只与边界上振荡器的振荡频率有关。利用耦合本振阵列形成均匀相位分布的这一属性,调整耦合本振阵列边界上的振荡器振荡频率,改变耦合本振相邻阵元的相移,实现波达方向估计。同时对三角形耦合阵列的稳定过程、波达方向估计进行了计算机仿真,验证了理论分析结果。

| Abstract: | The paper presents the local oscillator arrays using the symmetry triangle coupled oscillator arrays,and analyzes its phase control principle.It is deduced that the phase distributing is symmetrical when coupled-LO arrays is synchronized,and the phase step between coupled-LO array units only related to the boundary oscillator frequencies.According to this attribution we obtain DOA estimation by adjusting the boundary oscillator frequencies of triangle coupled-LO arrays.We simulate the synchronization proces... |
