CEVA Cumulant based Eigen Vector Approach to 2 D DOA estimation is proposed.New algorithm determines elevation and azimuth at the same time.Spatial smoothed cumulants increase the insensibility to spatial correlated Gaussian noises.It is also proven that particular chosen cumulants make proposed algorithm even insensitive to spatial white non Gaussian noises.Simulation results show the remarkable higher performance with comparison to those obtained from MUSIC method.
