: 提出一种基于Toeplitz 矩阵重构的相干信号源DOA 估计算法首 对各 个阵元的接收
数据与参考阵元(第一个阵元) 的接收数据的相关函数进行排列,形成Her itian Toeplitz 矩阵,
然后通过奇异值分解可以得到信号子空间和噪声子空间,从而实现相干信源的DOA 估计该
算法在不减少阵列有效孔径的情况下, 增加了可估计相干信号源数目,并在低信噪比条件下能
够得到较好的估计性能, 计算机仿真结果证实了算法的有效性

Abstract:A new DOA esti ation algorith of coherent signalsbasedonToeplitz atrix reconstruction
is proposed. This algorith is i ple entedthrougharranging the received data correlation function of
each array ele ent and reference array ele ent ( the first array ele ent) and for a Her itian
Toeplitz atrix firstly. Then through the singular value deco position of the atrix, the signal sub-
space and noise subspace can be arrived in order to achieve the DOA esti ation of coherent sources.
The new approach,without reducing the aperture of array, increases the ability of discern ent under
the sa e SNR, the si ulation results show that the proposed ethod is effective.
