We propose a novel joint estimation algorithm for range

frequency

and two-dimensional (2-D) direction-of-arrival (DOA) of each narrowband source in the near field.The proposed method constructs four matrices using the higher-order cumulants of the properly chosen sensor outputs

and forms three new ones using the four matrices

then estimates the source parameters from the new ones’ eigenvalues and the corresponding eigenvectors.In comparison with the conventional methods

the proposed approach efficiently uses the array aperture

and pairs parameters automatically.Finally

the simulation results are presented to validate the performance of the proposed method.
