AbstractA technique that enables array error correction by replacing the signals from failed elements with processed signals derived from operating elements. The procedure is shown to be useful in a multisignal environment. Expressions are derived that give the signal to noise ratio of arrays with any number of failed elements with replaced signals. These relations are used to investigate the counterintuitive limiting case in which all the signals of an array are replaced by the reproduced signals.
