[Abstract]:In this paper, a wide linear adaptive beamforming method based on 4 elements is proposed. On the basis of constructing the output of single array element by using 4 element number, the noncircular characteristic of joint signal is obtained by fully mining three involutive information of 4 element number. A 4-element numerical domain involutive and augmented signal model is established, and then the 4-ary number domain wide linear adaptive beamforming is realized. Compared with the traditional four-element beamforming technique, the performance of the proposed method for non-circular signals is improved significantly, and the array virtual aperture expansion can be realized, and the degree of freedom of interference suppression by adaptive beamforming can be increased. The performance of the proposed beamforming method is verified by simulation experiments.
