Abstract

Direction-of-arrival (DOA) matrix method has been proposed for two-parallel uniform linear array (TPULA) due to its advantages in pairing match of 2D angle estimation. However, DOA matrix is constructed only based on sub-covariance matrices, so both the estimation ability and the maximum identifiable source number are limited. An improved DOA matrix method (DMM) is proposed in this paper, which extracts extended subarrays to construct the DOA matrix. Compared to conventional method, the proposed algorithm can not only improve the performance in 2D angle estimation but also increase the maximum identifiable source number. The simulations results verified the advantages of the new approach.
