本文提出了一种利用虚拟双线性平行阵的循环累量域二维波达方向 （ＤＯＡ）估计算法。该算法构造了一个虚拟ＤＯＡ循环矩阵（ＶＤＯＡ Ｃｙｃｌｉｃ　Ｍａｔｒｉｘ），井基于此矩阵进行ＤＯＡ估计。理论分析表明，通过对虚拟ＤＯＡ循环矩阵的特征值分解，就可以得到源信号的二维ＤＯＡ估计。同时由于循环累量对高斯噪声的自然盲性和对信号的选择性，该算法具有循环域和累量域ＤＯＡ估计算法的良好性能。该算法的另一特点是可以提供虚拟扩展孔径，提高了ＤＯＡ估计的性能． In this paper, we propose a cyclic cumulant domain two-dimensional direction of arrival (DOA) estimation algorithm using virtual bilinear parallel arrays. The algorithm constructs a virtual DOA cyclic matrix (VDOA Cyclic Matrix) and performs DOA estimation based on this matrix. Theoretical analysis shows that by eigenvalue decomposition of the virtual DOA circulant matrix, the two-dimensional DOA estimation of the source signal can be obtained. At the same time, due to the natural blindness of Gaussian noise and the signal selectivity of the cyclic cumulant, the algorithm has the good performance of the DOA estimation algorithm of cyclic and cumulant domains. Another feature of this algorithm is that it can provide virtual extended aperture and improve the performance of DOA estimation.
