Abstract

This paper proposes a subspace-based array shape estimation method using a single reference source in nearfleld. First, from the nearfield source received by hydrophones, setting the degree of freedom of the perturbation equal to one, a nearfield covariance matrix is derived. Second, a simplified subspace fitting method that requires only a single reference source is proposed. From the numerical experiments, the proposed method shows good performance in estimating the shape of the array using only a single reference source wherever the source exists.
