摘　　要：为了估算基于均匀圆阵列(UCA)的三维(3D)单基站测向(方位角、仰角和区间),提出了一种改进的适用于三维场景的闭环式算法。该算法是一种计算过程较简单的通用算法,无需使用均匀圆阵列的中心对称性,没有任何传感器数量的限制,只需要一个单独的最小平方程序用于估算基站的位置,并可以估算所有的三维测向参数。实验结果表明,相比多种类似算法,所提算法的性能可与三维MUSIC算法的性能相媲美,且计算复杂度更低,实现速度更快。In order to estimate the three-dimensional （3D） single base station direction （azimuth, elevation and range） based on uniform circular array （UCA）, an improved closed loop algorithm was proposed for 3D scene. The algorithm is a general method whose calculating process is simple, and there is no need to use uniform circular array of central sym- metry. There are no restrictions of any number of sensors, a single least square procedure is noly required for estimation of the base station location, and it can estimate all three dimensional direction parameters. The experimental results show that, compared to a variety of similar algorithms, the performance properties of algorithm and 3D MUSIC algo- rithm is comparable, it has low computational complexity and its implementation speed is faster.
