摘要

该方法基于协方差矩阵的信号特征向量是包含DOA信息的方向向量的线性组合。通过对信号特征向量组合的元素序列进行高分辨率频率估计，该方法在低信噪比下具有更好的性能。例如，它比空间平滑MUSIC和最小norm对噪声的鲁棒性高约5db。

A novel approach for robust high-resolution DOA estimation

The proposed method is based on the signal eigenvectors of the covariance matrix being a linear combination of the direction vectors which contain the DOA information. By applying a high-resolution frequency estimation algorithm to an element sequence of a combination of signal eigenvectors, the proposed method has better performance at low SNR. For example, it is about 5 dB more robust to noise than spatial-smoothed MUSIC and Minimum-Norm.<>
