Abstract
The orthogonal method is used to improve the patterns of the linear array in the presence of failed elements. Reconfiguration of the amplitude and phase distributions of the remaining elements can partially compensate for the failed elements and thus reduce the sidelobe level. Numerical results are presented to illustrate the effectiveness of the method. The effect of the number of failed elements, the distance between the elements and the shape of the desired pattern is demonstrated through this paper.
