    Abstract: A method and a system are disclosed compensating for failed elements in an antenna array. The method assumes that at least the amplitude and, in most cases, the phase of, at least, some of the individual elements can be controlled to some extent. If one or more of the antenna array radiating elements are failed, at least some remaining elements are used to correct for this. The amplitude and phase radiation pattern of one of the failed elements is then synthesized using K of the remaining elements. The resulting excitation from this synthesis is superimposed on the failed array excitation at the positions of the K remaining elements. This procedure can be repeated for all the failed elements using the principle of superposition.
