A generalized acquisition scheme for vector cross-product direction findingwith spatially spread vector-sensor components

In this paper we propose a generalized non-collocated electromagnetic (EM) vector-sensor configuration allowing the use of the vector cross-product direction finding scheme. The presented work extends the results and the philosophy of [1] to a more general array configuration. We provide a sufficient condition ensuring identifiability of source DOA parameters and propose a novel algorithm allowing the DOA estimation for inter-antenna spacing larger than λ/2. The effectiveness of the proposed approach is illustrated by numerical simulations.
