两种均匀圆阵特性对比分析研究

摘要

To analyze the characteristics of two different uniform circular arrays(UCAs), two kinds of different UCAs resolution and CRB functions are derived on the basis of the study of array structure and data model.Then, basing on the study of the functions, the factors that influence the values of the resolution and CRB are systematically studied.A lots of the simulations are done to certify the theoretical analysis.The effort lays the foundation for further analysis.%为了分析水平放置和竖直放置的两种不同的均匀圆阵的特性,首先在研究均匀圆阵阵列结构和数据模型的基础上,分别推导了两种不同均匀圆阵分辨率公式和克拉美罗下界(CRB)表达式.随后,基于导出的公式,系统研究了影响两种不同圆阵的分辨率、方位估计的CRB下界值的因素.最后,进行了大量的计算机仿真实验,验证了上述理论分析,为进一步深入研究均匀圆阵的固有特性打下了基础.
