摘要：
Most of the existing eigen-decomposition based,localization methods use the plane-wave assumption when estimating the direction of arrival of multiple sources. In this paper, we present a four-order cumulant based ESPRIT like method for passive localization of near-field narrowband non-Gaussian sources using a centro-symmetric cross array. The proposed method uses the multiple-rotational invariance among certain cumulant-domain signal subspaces for 4-D parameter (carrier frequency, elevation, bearing and range) estimation of multiple sources. The method does not require any spectral peak search, only needs I-D parameter pairing, and can be applied to additive Gaussian noise environment. The performance of the proposed method is verified by computer simulations.
