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.

Key words: 3D direction finding parameter estimation,Uniform circular array (UCA),Array transform,MUSIC
