摘　　要：针对三维空间高分辨率阵列测向的研究，本文以电磁波传播理论为基础，首先建立了任意阵形的天线阵列对三维测向空间内多信源测向的数学模型。然后以该模型为基础，用阵列测向算法─—ＭＵＳＩＣ算法，对三维空间内分布的多目标实现了实时、高分辨率测向。最后，进行了计算机模拟，其模拟结果与理论结果达到了较好的吻合。In this paper, the research on high resolution array direction-finding for three spatial space will be based on electromagnetic wave propogation theory. Firstly, a mathematical model is established, which is suit for antenna arrays with any shapes to measure the direction of arrival for distributed sources in three spatial space. Secondly, based on the mathematical model, a real time and high resolution direction-finding is realized for distributed sources in three spatial space with array antenna direction-finding algorithm──MUSIC algorithm. Finally, the computer simulation is proposed and it has identical results with the theory.
