| 摘 要： | 传统的基于相干信号空间聚焦的宽带DOA算法具有良好的空间分辨能力、较低的信噪比门限,但必须通过角度预估计来构造相应的聚焦矩阵。文中提出了一种不需要角度预估的相干宽带DOA算法,直接利用阵列接收数据构造聚焦变换矩阵,避免了预估计角度对聚焦变换的影响,同时降低了算法的运算量。计算机仿真表明该算法是有效的。 |

| Abstract: | The conventional wideband direction-of-arrival(DOA) algorithms based on coherent signal-subspace focusing have excellent spatial resolution ability and low signal-to-noise threshold.However,they must rely on the preliminary angle estimates to construct the corresponding focusing matrices.This paper presents a coherent wideband DOA algorithm without using the initial estimates of angles.The proposed method processes the array output vectors directly to construct the focusing matrices that aim at avoiding the... |
