摘要：

A new approach for high-resolution direction-of-arrival (DOA) estimation of coherent wideband signals is proposed. The approach is based on the projection of the two-dimensional spatial-temporal DFT of the received signal. The projections are used to construct narrowband covariance matrices having the same signal subspace which are then combined to yield the array covariance matrix. The array covariance can then be used by any signal-subspace eigendecomposition algorithm. The proposed approach does not require any preliminary estimates of DOA's and is not restricted to particular source models.
