摘　　要：文中把阵列流行内插宽带测向算法应用到均匀线阵上,并给出了求变换矩阵的另外两种方法。与通常的宽带信号子空间方法相比,提出的算法不需要对波达方向进行预估计,且具有对相干宽带信号进行测向的能力。理论分析和仿真实验证明了文中测向算法的有效性。Wide-band direction finding is an active topic of research in signal processing field. This paper applies the array manifold interpolation wideband direction finding algorithm on uniform linear array, and gives other two methods of seeking transformation matrix. Compared with the traditional wideband signal sub-space direction finding algorithms, the proposed algorithm does not need pre-estimating of direction of arrival, and can handle coherent sources. Theoretical analysis and extensive simulation results demonstrate that the algorithm has goof performance.
