Abstract :
In this paper, we propose a new near-field source localization algorithm without any spectral peak searching or parameter pairing. Firstly, based on fourth-order cumulant of the outputs of a uniform linear array (ULA), we derive a multiple invariance-sensor array processing (MI-SAP)-type data model using the formed cumulant matrices. Secondly, the DOA, range, and frequency parameters are estimated from the matrices got via trilinear decomposition of three-way array. Finally, simulation results are presented to validate the performance of the proposed method
