| Abstract: | In this paper, an algorithm used to estimate the signal DOA with MNM (minimum-norm method) by means of the augmented data matrix in SVD (sigular value decomposition) is introduced. The augmented data matrix is constructed with received data and their conjugates. It is pointed out that this augmented data matrix would improve the eigenvalue distributions of the covariance matrix, and then make the estimation performance of signal DOA (direction of arrival) better. Finally, the simulated results confirming the theoretical analysis are pre- sented. |
