Description: Failed elements will des仃oy the amplitude and phase distribution and yield an increase in the sidelobe level．It call
seriously degrade the performance of art towed linear array．Beamforming in the presence of element failure can be seen as a
non-linear least squares fitting question and the computations ale difficult．Aimming at this problem,an optimized method of element
failure correction based on genetic algorithm is presented basic principle is to match the array response to a desired response
over the mainlobe regions and minimize the weighted mean—square value of the response over the sidelobe regions．At the same time,
weights offailed elements are forced to zero．Result ofthe simulation indicates that the method is feasible and effective．
