Abstract The traditional Constant Modulus (CM) beamformers are found to degrade in impulsive noise environment. In this paper， -stable distribution is introduced as a model of impulsive noise. And a robust CM beamformer is proposed. Steady α-state of the beamformer is analyzed based on fractional low-order statistics theory. Computer simulations verify the analysis.

Key words： Constant modulus array;Beamformer α-stable distribution;Fractional low-order statistics theory
