一种快速子空间测向算法

A Fast Direction Finding Algorithm Based on Subspace

考虑用户先验知识提出一种快速子空间测向算法,构造了方向约束的相关相减多级维纳滤波器(MCSA-MSWF)方法,此方法在降低特征分解的基础上进一步降低了谱峰搜索的运算量,且克服了单纯基于多级维纳滤波器测向算法期望信号不准确的问题。仿真表明,该算法在低信噪比、小快拍数情况下具有更好的估计性能。

A fast algorithm for direction -of- arrival（DOA） estimation is proposed in this paper by earlier experience. A direction - bind multistage wiener filter（MSWF） implemented by the correlation subtraction algorithm is constructed. In addition, computer simulation shows that this method can be applied where only a few samples are available and the signal to interference plus noise ratio is very low.
