摘　　要：针对DS-CDMA系统,提出一种基于三个相互垂直阵列结构的二维DOA估计算法,结合CDMA系统的特性,利用其中一个阵列与另外两个阵列组合分别估计一维DOA,该算法结构简单,分辨率高,弥补了传统MU-SIC的不足,能改善DOA的估计性能,仿真结果表明了此算法的可行性和有效性。Based on three orthogonal linear arrays within DS - CDMA system, this paper proposes a method to estimate 2D - DOA. This method utilizes one of the three linear arrays to pair the 1 - D DOA which is estimated by the other two linear arrays respectively. Because of the sufficient use of the characteristics of CDMA and 2 - D processing, it can polish MUSIC algorithm and improve the capability of DOA estimation. The simulation results show the feasibility and effectiveness of the method.
