A method for adaptive beamforming based on model transformation is presented to overcome beam distortion with colored noise in this paper. The colored noise field is changed into the white one through the instrumental variable, further, the conventional method can be used. The proposed method is feasible for adaptive beamforming in colored noise, and numerical simulations are carried out.
