Deterministic Blind Identification in Antenna Array Processing
Résumé
The estimation of directions of arrival is formulated as the decomposition of a 3-way array into a sum of rank- one terms. However, a low-rank tensor approximation does not always exist. We propose an optimization technique based on differentiable angular constraints on the factors, ensuring the existence of the low-rank tensor decomposition. The efficiency of the proposed algorithm is demonstrated via numerical simula- tions, and compared to Cramer-Rao bounds.
