A method for compensating for lateral distortion (30) in a moving linear array (20) using a frequency domain beamformer, comprising the steps of measuring the instantaneous lateral distortion (30) of the linear array (20) at discrete points (40) along the array (20), corresponding to array element locations, calculating a shading weight for each of the discrete points (40) along the array (20), corresponding to array element locations based on the instantaneous lateral distortion (30) at each said point (40) and calculating the compensated beam magnitude by multiplying said shading weight into the frequency domain beamformer equation. <IMAGE> |
