一种基于方向响应函数的MUSIC改进测向算法

An Improved MUSIC Direction-finding Algorithm Based on the Bearing Response Function

提出了一种新的DOA估计算法,称之为SMUSIC测向算法。算法充分利用了阵列自相关函数的标准子空间处理模型和另一种信号加干扰的处理模型之间的线性代数结构特点。SMUSIC算法具有能同时估计来波方向和每个信号的功率的特点。仿真结果证明了SMUSIC算法比传统的MUSIC算法的优越的性能。

This paper proposes a new direction of arrival （DOA） estimation algorithm which is called SMUSIC. The estimator is based on a linear algebraic connection between the standard subspace model of the array correlation matrix and a special signal-plus-interference model. SMUSIC has the advantage that it can estimate the DOA and the power of each source simultaneously. Simulation results show that SMUSIC has better performance than MUSIC.
