| 摘 要： | 通过对均匀阵列下二维TLS-ESPRIT算法的研究,将一维ESPRIT改进算法推广到二维领域,在二排平面均匀直线阵模型中使用同一排几何阵列构造两个子阵列,即将阵元为M的阵列够造成由前M-1个阵元构成的子阵列和后M-1个阵元构成的子阵列,从而增加了阵列的有效孔径,提高了信源波达方向的估计精度,并通过MATLAB仿真,给出了不同信噪比情况下,改进算法与原算法的性能比较,证实了该算法的有效性。

| Abstract: | Based on the study of 2d TLS-ESPRIT algorithm,one-dimensional improved ESPRIT algorithm is popularized to 2d domain.This method uses the same array geometry to construct two subarrays in the two row uniform linear array model,that is to say,the whole M array is divided into two subarrays composed of the front M-1 subarray and the behind M-1 subarrays,thus to increase the effective aperture of the array and improve the estimation precision of DOA.The simulation with MATLAB indicates that the improved algorit... |
