摘要: |
构造了一种可以进行高分辨二维波达方向估计的累量域波达方向矩阵。利用该矩阵的特征值和特征向量,就可以求出信号源的方位角和俯仰角。同其它的波达方向矩阵法相比,放宽了对阵列结构的要求,提高了阵列孔径的利用率。同时,由于采用了累量来构造波达方向矩阵,因此新方法具有对高斯噪声的自然盲性。 |

Abstract: |
A cumulant-based direction-of-arrival(DOA) matrix is proposed, whose eigenvalues and eigenvectors can be used to get the estimates of signal directions. It differs from other doa-matrix methods in that it relaxes the requirements for array geometry, makes better use of the array aperture and is based on cumulant, which makes the new algorithm insensitive to Gaussian noise. |
Keywords: Direction-of-Arrival(DOA) Estimation, Cumulant, DOA Matrix |
