摘要 针对特定应用环境对阵列结构的特殊要求,以及一维线阵无法完成多维空间谱估计的问题,建立了空间任意阵列的数学模型,推导了空间任意阵的MUSIC算法,分析了算法的性能,实现了空间目标信号波达方向的方位角和俯仰角二维联合估计;以空间任意四元阵为例,通过计算机仿真,对比研究了3种不同阵列结构的MUSIC算法定向性能,仿真结果证明了算法的正确性和有效性。 For some particular application environment, linear array and planar array can not meet the requirements. In this paper the high resolution Direction--Of--Arrival (DOA) estimation method--Multiple Signal Classification (MUSIC) algorithm for arbitary array is deduced. Computer simulation for the performance comparison between the nonplane quaternion array and planar array is demonstrated. Some conclusions of MUSIC performance for different array are reached.
