Abstract
This paper presents a beamforming algorithm which offers robustness against sensor position errors in the data-independent arrays, such as endfire array, Dolph-Chebyshev and Taylor array. Simulations show that the new method is capable of enhancing or keeping the directivity of the average power pattern as well as reducing the MSE in perturbed situations
