Abstract

This paper proposes a new algorithm based on parallel factor(PARAFAC) analysis for direction of arrival(DOA) and range estimation of near-field cyclostationary sources.We compute three third-order cyclic moment matrices using the uniform linear array outputs.A parallel factor model is constructed in the cyclic statistics domain and solved via trilinear alternating least squares(TALS).Both DOA and range of each source can be obtained without spectral searching and pairing paramenters.This algorithm can effectively suppress the additive stationary noise with any distribution and the cyclostationary interference.The simulation results of the root mean square error (RMSE) confirm the satisfactory performance of the proposed method.
