Abstract
© 1994 IEEE. A new technique for phasing coherent arrays is described for the situation in which independent realizations of an object's far field are measured, with each measurement corrupted by a different phase error. The method is similar to the imaging correlography technique in that an estimate of the object's autocorrelation is obtained by correlating the far-field intensities. However, in contrast with imaging correlography, this information is then used to estimate the phase errors for each realization, and the phase-error estimates are used to phase the array and form an estimate of the object.
