DOA ESTIMATION FOR POLARIZED SOURCES ON A VECTOR-SENSORARRAY BY PARAFAC DECOMPOSITION OF THE FOURTH-ORDERCOVARIANCE TENSOR

摘要

In this paper we propose a novel stochastic algorithmfor direction of arrival (DOA) estimation of polarizedelectromagnetic sources impinging on a six-componentvector-sensor array, based on the PARAFAC decompositionof the fourth-order covariance tensor of the polarizeddata. The Cramér-Rao bound is derived and theperformance of the proposed method are compared to aprior trilinear deterministic version of the algorithm [1]and to MUSIC for polarized sources [2].
