Abstract
In this communication, a new method is proposed to estimate the central direction-of-arrival (DOA) of multiple incoherently distributed noncircular sources from using the received data in two closely spaced uniform linear arrays. Both the received data vector and its conjugate are utilized to estimate the extended cross-correlation (CC) matrix. Singular value decomposition is then applied on the extended CC matrix to obtain the left and right singular vectors. Subsequently, the central DOA is estimated by using the left and right singular vectors associated with the largest singular values. The effectiveness and performance of the technique are accessed through numerical results.
