Blind joint angle and frequency estimation based on uniform rectangular acoustic vector sensor array

A novel algorithm has been proposed for joint angle and frequency estimation based on uniform rectangular acoustic vector sensors array. The joint angle and frequency problem is linked to a parafac quadrilinear model. Exploiting this link, it drives a quadrilinaear decomposition-based joint angle and frequency algorithm. This proposed algorithm has improved angle and frequency estimation compared to ESPRIT method and parafac trilinear decomposition method. Simulation results illustrate performance of this algorithm.
