摘要
文中在MU S IC算法的基础上,建立了平面任意形状阵列二维超分辨测向的数学模型及通用算法。针对不同天线阵列结构对二维测向性能的影响问题,分别以双排均匀线阵、均匀圆阵、均匀正方形阵和均匀L阵为模型进行了计算机仿真实验,并对这几种阵列的二维测角精度和稳健性进行了较全面的比较分析,得出了较理想的阵列设计方案。
Based on MUSIC algorithm, a mathematical model of two-dimensional DOA estimation on an arbitrary plane array is established. In order to study the different performance of 2-D DOA estimation on different plane array, the double-row uniform linear array, the uniform circular array, the uniform square array and the uniform L array have been put into emulation. The precision and stability analyses of 2-D DOA estimation on these arrays are presented. Finally, the suitable array form is given.
