| 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。

| Abstract: | 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 symmetry.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 algorithm is comparable,it has low computational complexity and its implementation speed is faster. |
