摘要
MUSIC算法是一种子空间分解算法,它的各种性能已被广泛研究.在信号波达方向估计领域,MUSIC算法的应用,形成了MUSIC波达方向估计算法.实际应用中,MUSIC波达方向估计算法,拥有超分辨能力的同时,也存在原理性缺点——MUSIC空间谱不能反映目标信号的相对强度.文中在前人工作的基础上,对MUSIC波达方向估计算法进行理论分析,提出了有效的改进方法,并通过仿真试验证实了分析的正确性.
The MUSIC algorithm is well known for its high resolution capability and various aspects of its statistical performance have been investigated. Application of MUSIC algorithm to narrowband direction-of-arrival （DOA） estimation can＇t take the advantage of signals＇ relative intensity. In this paper, the theory of MUSIC algorithm is studied to impose an improvement of the MUSIC algorithm. Computer simulations have been performed to confirm the validity of the theory.
