2D-DOA Estimation for Coherent Signals via a Polarized Uniform Rectangular Array

Zhe Zhang et al.

Summary: This letter proposes a method to estimate the 2-D direction-of-arrival (DOA) using a polarized uniform rectangular array (URA) under multipath propagation. The method establishes a parallel factor (PARAFAC) model that incorporates spatial response matrices, a polarization response matrix, and a source matrix. By taking the KhatriRao product with a full column rank factor matrix, the rank-deficiency of the source matrix is resolved, and three rearranged PARAFAC tensors are obtained. The estimation of 2D-DOA is then performed using the vector cross product-auxiliary rotational invariance technique (VCPARIT), which shows superiority over existing smoothing methods in terms of estimation accuracy.
