摘要
提出一种适用于L型阵列的基于Root-MUSIC的二维DOA估计算法。该算法先利用L型阵列的两个相互垂直的线阵独立的估计波达方向,然后利用该L阵构造二维MUSIC谱峰搜索表达式实现先前两个独立线阵计算出来角度的配对。本算法不仅具有MUSIC算法高分辨率的优点,还有运算量小、方法简单的特点。
A Root-MUSIC based method for two-dimensional direction estimation using an L-shaped array is proposed. The method converts the 2-D estimation into two 1-D problems using output data of two perpendicular linear arrays in the L-shaped array. A general method of pair-matching for 1-D parameters is also proposed. This algorithm not only enjoys high resolution features as MUSIC does,but also has the advantages of simplicity and small complexity.
