Abstract

This paper proposes a multidimensional (multi-mode) tensor model for the electromagnetic vector-sensor (EMVS) array to make full use of the multidimensional structure of the data.The mode-

signal subspace is defined based on this model.With the projection to the mode-

signal subspaces

a novel algorithm

which incorporates the refined signal subspace and the traditional MUSIC algorithm

is then presented.The proposed technique exploits the inherent multidimensional structure information for increased parameter estimation accuracy.Simulations show the superiority of the proposed algorithm to the traditional one.
