本文回顾和比较了三种不同的线性代数信号子空间技术的到达角估计。这些方法包括多信号分类（MUSIC）的多项式矩阵方法、参数化空间协方差矩阵方法和应用于MUSIC的基于自聚焦的相干信号子空间估计版本。这些方法表示在多项式时空协方差矩阵和多项式特征值分解的框架，从而突出了它们的共性和差异。仿真结果比较这些宽带到达角估计方法的精度。
This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix approach, and an auto-focussing based version of coherent signal subspace estimation applied to MUSIC. These approaches are expressed in the framework of polynomial space-time covariance matrices and their polynomial eigenvalue decomposition, thus highlighting their commonalities and differences. Simulation results comparing the accuracy of these broadband angle of arrival estimation methods are presented.
