Abstract :
This paper proposes a novel estimator for two dimensional angles of arrival of multiple narrowband sources using two parallel uniform linear arrays (ULAs). Unlike the previous DOA matrix method, it is based on a reformulated signal model and takes advantage of the special structure of the arrays to estimate more sources. In addition, spatial smoothing technique is used to extend the proposed method to estimate coherent or highly correlated signals
