| 摘 要： | 波达方向估计是智能天线的重要功能之一,对于相干信号角度模糊问题通常严重影响了方向判断的精准度.文中根据一维空间平滑基本理论和算法,对二维六边形阵列相干信号MUSIC算法波达方向估计问题进行了理论分析和仿真实验,提出了平面六边形阵列到十字形阵列的变换方法,成功地把一维平滑技术应用到平面六边形阵列,仿真表明,这种变换可以有效地消除相干信号的角度模糊问题.

| Abstract: | Estimation of signal direction of arrival(DOA) is one important function of adoptive antenna.The fuzzy angle in coherent signal environment of DOA estimation could seriously affect the estimation precision.Based on 1-D spatial smoothing theory this paper analyzes an algorithm for 2-D angle estimation in coherent source environment of hexagonal array and simulations were carried out.A method transforming the hexagonal array to cross-shape array successfully applied spatial smoothing technique to 2-D angle es... |
