Abstract

The paper deals with planar antenna arrays, such as circular, octagonal, hexagonal and rectangular, for the task of direction-finding on azimuth and elevation angles. The boundaries of the Cramer-Rao are calculated for different situations, including the location of signals in azimuth and elevation planes, and signal-to-noise ratios. Each antenna array consists of the same number of omni-directional antenna elements equal to 24, the distance between which is half the wavelength. In addition, the expressions for the steering vectors of two types of asymmetric antenna arrays, i.e. arcuate and L-shaped are given. Their influence on the direction-of-arrival estimation accuracy is considered, and the exact expressions of the Cramer-Rao boundary are given. It is established that the best geometry is arc-shaped.

非对称形式平面天线方位角无线电测向的Cramer-Rao界估计
本文研究了平面天线阵(圆形、八角形、六角形和矩形)在方位角和仰角上的测向任务。计算了不同情况下的Cramer-Rao边界,包括信号在方位角和仰角面的位置以及信噪比。每个天线阵列由相同数量的24个全向天线单元组成,各天线单元之间的距离为波长的一半。此外,还给出了两种非对称天线阵列(即弓形和l形)的转向矢量表达式。考虑了它们对到达方向估计精度的影响,给出了Cramer-Rao边界的精确表达式。确定了最佳几何形状为圆弧形。
