针对未知互耦和空间色噪声共存的双基地多输入多输出(MIMO)雷达,提出了一种新的基于协方差张量的稳健角度估计方法,研究了双基地MIMO雷达的DOD和DOA联合估计问题。在所提出的方法中,首先构造一个三阶张量来捕捉接收数据的多维特性。然后利用色噪声的时间不相关特性和互耦合矩阵的带状复对称Toeplitz结构,构造了一种新的四阶协方差张量,以消除空间色噪声和互耦合的影响。在利用高阶奇异值分解(HOSVD)技术得到稳健的信号子空间估计后,利用旋转不变技术实现DODS和DOA。与现有的基于HOSVD的子空间方法相比,该方法能够提供更好的角度估计性能,并能自动联合进行DODS和DOA。数值实验结果验证了该方法的有效性。
This paper deals with joint estimation of direction-of-departure (DOD) and direction-of- arrival (DOA) in bistatic multiple-input multiple-output (MIMO) radar with the coexistence of unknown mutual coupling and spatial colored noise by developing a novel robust covariance tensor-based angle estimation method. In the proposed method, a third-order tensor is firstly formulated for capturing the multidimensional nature of the received data. Then taking advantage of the temporal uncorrelated characteristic of colored noise and the banded complex symmetric Toeplitz structure of the mutual coupling matrices, a novel fourth-order covariance tensor is constructed for eliminating the influence of both spatial colored noise and mutual coupling. After a robust signal subspace estimation is obtained by using the higher-order singular value decomposition (HOSVD) technique, the rotational invariance technique is applied to achieve the DODs and DOAs. Compared with the existing HOSVD-based subspace methods, the proposed method can provide superior angle estimation performance and automatically jointly perform the DODs and DOAs. Results from numerical experiments are presented to verify the effectiveness of the proposed method.
