摘要
本文推导了均匀圆阵作为接收阵时的相位模式空间，证明圆阵在相位模式空间可以等效为一个虚拟线阵，并把高分辨方位估计算法应用到均匀圆阵相位模式空间虚拟线阵波束输出．计算机仿真结果显示，波束域Root－MUSIC算法应用到虚拟线阵时可以获得良好的解不相关信源的能力，而波束域WSF算法则具有比模式平滑算法更佳的解相干信源性能。
?In this paper the phade mode space of a uniform circular array(UCA) when used as receiver is derived- A virtual linear array is formed in the phase mode space of UCA. High resolution bearing estimationalgorithms are applied to the virtual linear array Computer simulation results show that the beam spaceRoot-MUSIC can achieve good performance for weakly correlated source signals while the beam spaceWSF has better performance than mode space smoothing algorithm for coherent source signals.
