Abstract—Direction-of-arrival estimation is one of the most important issues in the signal processing field, and fourth-order cumulants are used for DOA estimation by the motivation of the attractive fact that the higher-order cumulants of all kinds of Gaussian processes are identically zero. Because of the complexity of the computation for fourth-order cumulant, downsizing the cumulant matrix has attracted great interests. Beamspace fourth-order cumulant matrices have been proposed and simulation results show that they have better resolution performance with less computation load than the corresponding ones in element space. In this paper, we emphasize on their experimental performance. Experiments of DOA estimation in water tank are carried out and the results confirm the previous conclusion.
